Basically, most if not all of my xvid transcoded content looks horrible on my new HD set. The set is DVI-->HDMI running 1680x1050 (screen's native resolution) and the avi files are 512x384 or 720x480. I'm watching them with mplayer in mythvideo.

EDIT: seems as though my PVR-250's capture files do this as well. They are 720x480 and played back using the internal player as I normally watch them.

The best way I can describe the distortions are horizontal lines that appear over areas of motion. Is this what I've seen people term as 'cutting'? Are there known work arounds for it?

Thanks!

Just did the same.

I upped my bitrate quite a bit and changed my playback settings to bob(2x) and one field as the secondary deinterlacer.

That and setting my videoscan to either detect or interlaced normal.

It's not perfect, but that's the best I could get. Anyone else have any tips as I am attempting to be cheap and not do hd just yet.

Sounds like de-interlacing artifacts. Try some different
de-interlacing methods (bob2x is reputed to look the best).

In any case, watching low-res stuff on a 1680x1050 panel is
always going to look bad. You can play with settings to make
it a little less bad, but you're never going to be happy with.
Start saving up for an ATSC/QAM tuner. In the meantime, sit
further away and squint. ;)

It may also be scaling artifacts. These are quite common when you're blowing an image up. Especially if the size relationships between the original resolution and the display resolution aren't simple (in this case simple means simple ratios). For example 1->2 or even 1->3 generally gives good results (although it may start to look blocky and pixellated, and 2 -> 3 generally isn't bad, but when you start to get say 3->7 or 32->105 you'll see serious effects from the scaling, especially if you're not using some kind of fairly good smoothing filter.

Where are the smoothing filters set and are there any recomendations? Is that the setting right before the playback profiles?

Thanks!

Thanks for the replies, all. When I use the mplayer that came w/ my Ubuntu 8.10 install on my desktop machine, I don't see these distortions AT ALL playing the same files with the same mplayer options.... the only differences are:

Desktop Machine
Distro: Ubuntu 8.10 amd64
X Manager: Gnome
Video Card: 8800GTS, 512 meg (PCI-E 16x)
Video Driver: v180.29
Monitor: 22" Samsung LCD, model T220 (2 ms)

Frontend Machine
Distro: KM R5.5
X Manager: Fluxbox
Video Card: 8400GS, 512 meg (PCI)
Video Driver: v177.14.x
Monitor: 22" Samsung HDTV, model LN22450A (8 ms)

Can anyone explain this? Is it the 8 ms response time on the HDTV that's messing with me?

EDIT: It's *NOT* the differences in the screens. I just hooked both of them up to my desktop machine (twinview) driving off my 8800GTS and I can play the same file in each monitor free of distortion.

Now it seems as though the variables are:

1) Video cards and/or drivers
2) mplayer version
3) Linux versions?
4) Something Gnome is doing that fluxbox isn't doing?
4) something I'm not thinking of....

I can put the 32-bit version of Ubuntu 8.10 on my frontend (spare HDD) and do this same comparison on the 8400GS (PCI) card to see. Again, suggestions are welcomed :)

When you're in TwinView mode and playing from your desktop machine, what resolution is the HDTV being driven at? Is it the same as the resolution you're running your frontend at?

Yes, it's the same: 1680x1050 (the HDTV's recommended resolution).

OK! I got Ubuntu 8.10 on the frontend machine, using the 180.29 drivers, and using the ubuntu mplayer, I do NOT see the distortions that I see when running R5.5 :(

Therefore, it's gotta be something in R5.5 that's causing these since I ruled out the hardware. I'll try two things under R5.5:

1) compile my own mplayer from source and see if that matters
2) try to update the drivers to 180.29

If both those fail, does anyone have a suggestion?

Could it be something that fluxbox isn't doing that Gnome is doing?

I wish I knew more to say conclusively that it couldn't be Fluxbox, but I wouldn't think so. It's worth trying to upgrade the drivers, and possibly mplayer.

I'd also triple-check (via xorg logs) that your KnoppMyth box is running at the same resolution AND the same refresh rate AND the same color depth that your Ubuntu box is running at. Just because you have your xorg.conf file set up a certain way doesn't mean it's doing something differently than you think it is... checking the xorg logs is the only way to know what it's really running at.

Well, the 180.29 drivers didn't help either.... Here is the damn /var/log/Xorg.0.log. You have to d/l it as a text file because it's too massive to post.

Two things: 1) Any time I see an xorg.conf like that I strongly recommend either deleting or commenting out EVERY EVERY EVERY line that has nothing to do with the resolution and bitdepth you want. I also recommend getting rid of multiple resolutions per line, particularly if you know you only want to run at the TV's native resolution. So in your case I'd get rid of, or comment out, all SubSection "Display" items with a bit depth other than the one you want (24). Even with "DefaultColorDepth" set to 24, I would just do that to be sure. And on your "Modes" line, get rid of all resolutions other than "1680x1050" My guess is that it's running at some odd bit depth but that's just a guess.

My second thing was going to be to use Nvidia macros to output a standard HDTV resolution like 1280x720 or 1920x1080, but if you really want to run at your TV's default resolution, you probably won't want to do that (although it will work just like any Blu-Ray player or set-top box would work with your TV).

I'd also recommend checking out the xorg logs on your Ubuntu setup and see if you can compare what's going on. The stuff where it finally says what resolution it's running at is way at the end.

Yeah, the ubuntu logs show 1680x1050 as do my KM R5.5 logs. I modified my xorg.conf as you suggested, but the results are the same wen viewing videos.

Here is my modded /etc/X11/xorg.conf

Code:
Section "ServerLayout"
    Identifier     "Layout0"
    Screen      0  "Screen0" 0 0
    InputDevice    "Keyboard0" "CoreKeyboard"
    InputDevice    "Mouse0" "CorePointer"
EndSection

Section "Files"
    RgbPath         "/usr/lib/X11/rgb"
EndSection

Section "Module"
    Load           "dbe"
    Load           "extmod"
    Load           "type1"
    Load           "freetype"
    Load           "glx"
EndSection

Section "ServerFlags"
    Option         "Xinerama" "0"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Mouse0"
    Driver         "mouse"
    Option         "Protocol" "auto"
    Option         "Device" "/dev/psaux"
    Option         "Emulate3Buttons" "no"
    Option         "ZAxisMapping" "4 5"
EndSection

Section "InputDevice"
    # generated from default
    Identifier     "Keyboard0"
    Driver         "kbd"
EndSection

Section "Monitor"
    # HorizSync source: edid, VertRefresh source: edid
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "SAMSUNG"
    HorizSync       26.0 - 68.0
    VertRefresh     23.0 - 61.0
    Option         "DPMS"
    Option "UseEdidDpi" "FALSE"
    Option "DPI" "100 x 100"
EndSection

Section "Device"
    Identifier     "Videocard0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
    BoardName      "GeForce 8400 GS"
EndSection
Section "Screen"
    Identifier     "Screen0"
    Device         "Videocard0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "metamodes" "1680x1050 +0+0"
    SubSection     "Display"
        Depth       24
        Modes   "1680x1050"
    EndSubSection
EndSection


Do you have an HDTV? I can upload a clip of this avi that looks like crap for you guys to see on your systems.

As mentioned earlier, it sounds like deinterlacing artifacts. Bob2x should solve this.

A few things I learned about bob2x with my nvidia card:

1. Disable QT. This made a huge difference.

2. Do not align the display to the screen. Set the stretch and screen offsets in the setup all to 0. Setting them to non-zero confused bob2x and the whole screen started wiggling.

3. Remove all the playback profiles except the one you have set up with bob2x. Not exactly necessary, but useful to make sure you are using the one you expect. You can add new ones later and test once it is working.

4. Don't use XVMC. Things have probably improved since I tried it, but I found it caused nothing but problems. Especially with the OSD.

Comparing to a DVD player on the same TV is probably a good test. I now have something that looks almost indistinguishable on my 28' LCD from the DVD player. I say almost as I do see some minor mottling in mostly black scenes that seem to be due to colour depth. I haven't fixed this, but rarely notice it.

Have you tried nvidia-settings or whatever that command is to get to the Nvidia controls.

It could be that something is messed up in there. Sorry I don't have the exact command but I know it's here on the forums.
