I am running R5F27 FE/BE and anything above 1024x768 results in HD video playback being liney/wavey. It plays at the right speed with no jittering.
Hardware:
P4 2.4 Ghz
ASUS P4P800E Deluxe
Nvidia GeForce FX5500
Dvico DVB HDTV+
TP Link Wireless card (Atheros chipset)
Have Tried with and without XvMC, different de-interlacing settings (turned off as well) and different resolutions.
Done quite a bit of searching so far, but haven't really found anything useful.
Everything works great aside from that, but looking to push my box to the next level with surround sound and eventually a far bigger tv. (SD in australia is stereo as far as I know)

I don't believe XvMC is working (OSD is still colour) but I don't think the system should need it. CPU load sitting at 50% Watching LiveTV
Edit: Appears that XvMC is working and HD is jittery with out it. Lines appear regardless of XvMC being turned on or off.
Side note: Should I ask this question in a different section, I always find it hard to pick the right one!

Seems to have about 400Mb ram free, but I have a couple spare 1 gig sticks I could chuck in and see if it makes a difference. May do that tomorrow night.
I have tried all the different de-interlace settings including turning it off, with no change.
On the whole the box works really really well, so in preference I'd like to just keep it as is for the time being (till I upgrade my main pc and the good parts in it can filter down) rather then just throwing hardware at it.

If xvmc is working the osd will be a gray scale.
However, since playback is smooth it dosn't seem like you need it.
What kind of connecttion do you have between the pc and the display device? What kind of display device?

I must have been dreaming when I thought I wrote that info in the first post 
Everywhere else the picture is perfect, including dvd playback (through xine) and videos streamed off a samba share over wireless (mplayer).
SD Playback is flawless, with the occasional stutter when the osd disappears (no biggie).
Oh and the OSD is greyscale, don't know how It wasn't before (I did add some stuff to my xorg.conf), is likely that it was grey and never noticed. Ultimately it seems XvMC is required for playback of HD to not stutter.

Anyone got any tips on taking screen dumps? I've tried a few different things, but keep getting a big blue box where the program is supposed to be! Figured I can post up an image showing what I mean, might help decode the problem.
My want for HD is growing now, they are starting to show different things other than whats available on SD in Australia. 
Done quite a lot of Googling, unfortunately to no avail at this point

Guessing I'm dead in the water on this one....
I have noticed on SD (I was sitting close to the TV the other day) that it also has lines, but not horizontal like HD, but vertical and very faint.
As for HD, the lines are really noticeable and at the edges of the screen they point to form a sort of rounded half triangle shape. The OSD also suffers the same. So I would have to guess maybe I should be looking at my Xorg config???
If anyone even has the remotest suggestion I would be over the moon!

From my research I found that the way I spelt wavy was indeed incorrect which hindered my research:
wa·vey /ˈweɪvi/
–noun, plural -veys.
a wild North American goose of the genus Chen, as the snow goose (white wavey) or blue goose (blue wavey).
Should have been:
wav·y1 /ˈweɪvi/
–adjective, wav·i·er, wav·i·est.
1. curving alternately in opposite directions; undulating: a wavy course; wavy hair.
2. abounding in or characterized by waves: the wavy sea.
3. resembling or suggesting waves: a cotton material with a wavy pattern.
4. vibrating or tremulous; unsteady; wavering.
So the only goose in this equation was me
So further to search using the term 'wavy' I did find a lot more irrelevant information, but someone did have a little bit of trouble because minor tuning issues and I have managed to find a tuning table for Perth. Here's hoping
Perth Station.....Frequency....Video....Audio
Nine Digital........191625........512........650
Nine HD.............191625 .......522..........0
Ten Digital.........219500........512.......650
Ten HD...............219500........514.........0
Ten Guide ..........219500........513......660
Seven Digital.......177500......1537.....1538

I may be onto something, just have to figure out how to get those settings in.
It seems I missed testing all the HD channels, as ABC HD and SBS HD display as desired. Although I can't confirm they are broadcasting true HD so there is no way to tell if I'm barking up the wrong tree.

Nothing, I'm pretty stumped.

1. My new(ish) HD TV can't handle anything over 720p over hdmi (but it looks good).
2. The nvidia driver has HD modeline "720p" (and 720i, 1080i, 1080p) as a built-in
3. "nvidia-auto-select" is also a built-in, but caused the picture to be less than perfect
4. Option "TVStandard" "HD720p" should be used for DVB
5. DisplaySize seems to get ignored
Regarding your channels, you'll just need to scan and the new HD ones will be detected. Channel Ten definitely needs to be, since it's sacrificed several (ch 13, 14, 15) in favour of the new channel 1. If you need the channel data as a mysqldump I can give you mine (for Melbourne/Geelong).

Thanks Mike!
I think I'll try for the latest Nvidia Drivers, not sure whats packaged with R5F27.
I'm not outputting to a TV as such, it is a computer monitor, but it has HDMI instead of DVI. The native resolution of the screen is 1920x1200
http://www.viewsonic.com/products/deskt ... /vx2835wm/
It also has VGA, I'll dig out a lead and plug that in and see if it makes any difference.
I only setup the box in the last 2 weeks, so it has a recent scan of the channels and also the reception is pretty close to perfect. Channels 7, 9 and 10 all are liney. SBS and ABC are fine.

Hey techman,
I've had the mighty KM working with SD for a while now, and it goes into a VGA splitter (to a standard BENQ monitor and a BENQ projector). I've sucessfully viewed HD channels, but as the projector doesn't really deal with that sort of high def, i thought there wasn't much point.
I haven't rescanned recently to sort out the muck of the old HD channels, I might give it a go tonight.
The auto-scanning has tended to pickup all the channels ok in the past.
The reason for the post is that I'm in Perth also, so if you need some files/data from my box i can get it to you.
Cheers,
Nathan

Hey Nathan,
Thanks for the offer, it's nice to know of other MythTVers out there locally. Been running my current rig as my primary TV since R5D1, but toying around with it Early R5 days
I didn't much have use for HD before, as they never broadcasted proper HD anyway and I was outputting S-Video, kinda defeated the purpose. I got a HD capable screen now and they are broadcasting Proper HD, so it has given me motivation finally 
Leon

Coffee has kicked in now and the brain is functioning properly!
I might try outputting 720 and maybe 1080i as per Mikes suggestion, being HDMI input it should scale properly I would think... been treating it like a Monitor all this time, when it's supposed to be capable of being a telli!
Wonder if will be ok with 16:9 as it's a 16:10 screen. Fingers Crossed

Yeh, the whole TV thing (modelines, xorg.conf) confused the hell out of me, so was quite happy to stick with VGA monitor/projector combination. A mate in Perth has his mythbox working to a big telly, but i prefer not to tangle my little brain with such things..
Hope it works out...
