Not bad. Last time my son watched Star Wars Ep I there were some times when
you'd see the picture jump. I think I might be able to make it a little better.
I've been using Ogle thus far as I pretty much need menus for most of our DVD's.
I'm hoping to figure out how to fold it into Myth someplace.

I am still waiting for the Nemiah (sp?), hopefully it will do better in
performance than my crappy 800.

Made more progress last night with my EPIA rig. Got the channel changing script
working like a champ. I think I might add a command to turn on the rx before
every channel change as I want to make sure it's on for a late night recording
in case it gets turned off. (Which would be ironic because I'm the only one who
turns it off up to now!)

I still don't get how to use recording profiles, but I do see that Live TV and
Default affect Live TV (imagine!) and Recording respectively.

Was able to do Live TV with 352 x 240 resolution. CPU utilization totalled
around 85% most of the time.

Is there a place where all the key mappings are detailed? I'm sure this software
can do things that I don't know about. (For example, how do I join a recording
that is in progress, in effect switching over to LiveTV from just Recording?)

Woo Hoo!

How do you think it would work just as a frontend? If you can do live TV at
352x240 it seems like you should be able to just do playback at 480x480 or
even higher.

Did you read keys.txt?

Also, recording profiles don't do much right now, other than the two

With the newer slim graphics driver it plays 480x480 just fine. 640x480
is pushing it but I also haven't spent any time trying to optimize the OS,
etc.. The hiccups I see are when you change channels and the OSD is up.
Once it is down, then playing is fine. Pause, rewind, ff all work great.

I have had some issues with various audio drivers though. The one shipped
by Via seems to work pretty well, but you have to use a supported distro.
The 2.4.20-ac kernel has a driver that works with xmms but not with
MythTV (video slows down then jumps ahead, no sound). The 2.4.21pre5-ac
works better, but I still have problems ("max headroom" effect). I also
changed some other stuff at the same time so I am still trying to narrow
down the cause.

I also have it booting over the net using PXELinux which works great. The
tricky part is getting your root partition set up correctly (which I am
still working on).

From what i recall 2.4.18 kernels had a known bug that disables interrupts.

You can't with the slim drivers. Maybe next version

Or try it with option "NoDDCValue"

How is your TV output with this motherboard?

I have this hooked up as my frontend, and the screen is over to the
right about an inch. I have tried using xvidtune but it does not seem to
move.

I am using Mandrake 9 with the slim driver, and things seem to be
running ok, just need to tweak things.
Mandrake 9 surprised me with the audio working with no problems, other
versions would not work right.
Tried 8.2 and the VIA drivers would not install, 9.1 R2 and the sound
was crackly.

Any tips from users using this board?

Thanks...
