Basically, I have performed multiple installs of Knoppmyth R5A26 and it pretty much works right out of the box on my M10000 with a 1000MHz Nehemiah CPU and PVR-250 with 256MB of RAM.

The problem is, the first few installs, I checked my CPU utilization and it was ~30% while watching live or time-shifting live TV (2% or so while recording or pausing live TV).

The last three installs, I average closer to 75% while watching live TV or time-shifting, still around 2% while recording or pausing live TV, with no hardware change. I am using the same install disk and modules and everything else.

The only thing I could think of was with the first few installs, even though the install instructions said not to (I noticed this later obviously), I created my user account as mythtv.

With my install properly configured (using a different user account name is the only change), is my CPU utilization about normal? I have tried lots of different MythTV installs and the Knoppmyth install behaved more like I was used to when I used the mythtv account, though it required more user interaction during setup, it's a small sacrifice to have significantly lower CPU utilization.

Also, I have been trying to use ICEWM and I can apt-get it after the install, but I can't get Myth to overlay the ICEWM toolbar.

Thanks

I performed another install of Knoppmyth using the user name "mythtv" against the instructions provided in the Knoppmyth setup. The myth setup behavior was more like what I was used to with Jared Wilson's Fedora guide AND the CPU utilization was ~30% again.

Now I am wondering if maybe TOP is goofy on the knoppmyth install because when installing Knoppmyth using the mythtv user name, the total CPU usage percentage (above the table of processes) closely mimics a total of the percentages in the table of processes.

Conversely, when Knoppmyth is installed correctly, using any user name other than mythtv, the total CPU usage percentage (above the table of processes) is about the same as before but a large amount smaller than the total of the percentages listed in the table of processes.

The other day, I tested the next release with an Epia (1.2 GHz model). Smooth install all the way. When to watch TV and I had top running in another xterm which I cycled to 14% CPU utilization. When I test on the Epia, the CPU utilization is always around 14%.

I added
Option "EnableAGPDMA" "true"
under
Section "Device" in my XF86Config-4 file and that brought my CPU usage down to around 55%

The only real problem I have had after a fresh install is that my TV is very green. When I turn Option "DPMS" "false" under Section "Monitor", that problem goes away.

Everything else is default from the setup, except I chose i686 modules. I am running a M10000 with a Nehemiah CPU, 256MB of Crucial PC2100 RAM, a PVR-250, a 200GB IDE Western Digital hard drive, and a standard slimline DVD-Rom.

Are there options under Myth that people are changing to lower CPU utilization?

Also, any input on configuring ICEWM to work?

Lastly, can there be a monitor hooked up and displaying Firefox or Xshells while MythTV is displayed on the TV?

Is Mythtv configured to used XvMC VLD?

I turned off deinterlace video option in MythTV settings and my CPU usage dropped to ~10%. Is that the case with your setup too?

As far as XvMC VLD, I'm not exactly sure how to check that.

Now I wonder how low CPU utilization will be if I installed Knoppmyth using the user MythTV again

Anyway, I have a few questions still unanswered

Browse through the setup menus under the GUI I believe it's under setup -> tv -> playback but my memory is a bit strained at the moment.

The value in the settings table is "UseXvMcVld". You can check it's current value using the following command as root:

+------------+------+----------+
| value | data | hostname |
+------------+------+----------+
| UseXvMcVld | 1 | mythtv |
+------------+------+----------+

is the response. I am guessing that XvmcVLD is enabled.

So is ~10% normal when not deinterlacing video? Or should I still be around 14% while deinterlacing video?

Other questions include:

Are there ways to add more fonts or myth themes? The built in themes/fonts seem a little small on my TV.

Can there be two different displays output on a Epia? MythTV output to the TV and Firefox or Xterms open on a connected monitor?

Is there a way to configure ICEWM to work with KnoppMyth?

The easiest way to fix the font sizes is to lie to the server about the size of your screen. See this thread in the forums: http://mysettopbox.tv/phpBB2/viewtopic.php?t=6118 and the font size how to on the wiki: http://www.knoppmythwiki.org/index.php?page=FontSizeHowTo.

also what type of deinterlace were you trying to do? bob is the only one that works with xvmc

Deinterlacing set to "Bob" raises CPU utilization to ~55%. No deinterlace CPU utilization is ~10%.

I will try the font trick today.

Thanks

So is 10% CPU Usage average for a 1GHz Nehemiah with deinterlacing off or should I be around 14% with deinterlacing on?

I have figured out almost everything else I have had trouble with thanks to other forums user posts.

Thanks everyone!

OK, so I updated my M10K (Nehemiah) to the newest BIOS (1.16).

I put in a different HDD (Samsung SP1203N) in my system to keep my old, working R5A26 build on the 200GB (Western Digital WD2000JB).

Otherwise, I only upgraded Knoppmyth to R5A30 and now it doesn't matter what Deinterlacing settings I use, I get ~30% CPU utilization. Even with Deinterlacing turned off, I get ~30%.

Is it possible with my BIOS upgrade and Knoppmyth upgrade that my CPU is throttling to the load it's subjected to?

What CPU utilizations are other people getting?

I have a M10K with a 1GHz Nehemiah
256MB PC2700 RAM
Hauppauge PVR-250
120GB Samsung HDD
generic DVD-Rom
in a Travala C137

BTW the idle CPU is ~40% according to top. Not sure where it's all being used though...

First, you can safely ignore most everything I have written in my own thread up until now, I appreciate everyone's help and patience but I am fairly new to this and have made many mountains out of molehills.

Second, I upgraded to R5A30.1 and it's......

AWESOME!!!

I added "Option EnableAGPDMA" "true" in XF86Config-4 and set DPMS to "false" (otherwise my TV is very green). Though I am not sure I needed to do the latter as my Epia is currently diconnected from my TV, easy enough to switch back though if it proves unneccessary. Any advise on this phenomena would be appreciated.

Otherwise a pretty much default install and OTA (over the air) broadcasts are showing at ~10% cpu utilization to mythfrontend using Bob setting for Deinterlace. I finally realized signal quality is a HUGE factor with CPU utilization, especially when deinterlacing.

Besides my earlier questions (ICEWM and not cloned dual displays), I only have one new question:

in top, my CPU "wa" percentage fluctuates wildly but averages around 50% and everything I have read on the Internet says that anything above 0.0% wa is bad. Can someone tell me if my number is bad or ok and if it is ok, why it's ok?

Thanks
