John H.,

First off, nice work on the X driver. It's pretty incredible to see the
progress that is being made by everyone in the ivtv development group, as
well as those that are developing MythTV.

Here's my setup:
  P4 2.4Ghz Celeron
  Gentoo Linux, 2.6.10 kernel, Xorg, KDE 3.3
  MythTV Backend/Frontend 0.18.1 (VBI turned off)
  1 PVR-350 and 2 PVR-250MCE's
  ivtv-0.3.6c
  X-driver ver 10.1
  TV-Out thru the 350 (NTSC)

Everything has been running wonderfully. TV recordings are great. Playback
thru the 350 of TV recordings is great. When I playback XVid, DivX, etc.
recordings through MythVideo are working much better with your new X driver
(before playing I intialize the decoder by playing back a TV recording in
MythTV). However, I've noticed the following:

- First I playback a tv recording to initialize the 350 decoder. I can
pause, ff, rew, etc. with instant results.
- I then go to MythVideo and playback recordings of various types. They
playback very well. I can start and stop them one right after the other. I
use mplayer to play them back and customize the command based on the video
that I am playing to get the correct aspect, etc. 'mplayer -fs -vo xv -vf
scale=720:-3,expand=720:480 <file>' and 'mplayer -fs -zoom -quiet -vo xv
<file>' are the two commands that I have employed in playback, depending on
the video file.
- When I go back to watching tv recordings after playing videos, things
become unstable. When I try to pause, ff, rew, etc. I have to wait a couple
of seconds for the system to respond. If I don't wait the system will become
unresponsive and the video continues to play without the ability to stop via
key commands and/or via the remote. I have to kill Mythfrontend to get it to
stop. Restarting the frontend doesn't fix the problem. 
- If I exit the tv recording successfully and then try to play a video in
MythVideo right afterword, I get sound but no video playback.
- Rebooting fixes everthing

It seems as though something is not getting reset properly. I don't know
whether it is the way that MythTV interacts with the drivers, the X driver
or ivtv that is the problem. Unfortunately I don't have any logs to give you
at the moment. Please let me know and I will send you any information that
may help point out where the problem may exist. Unfortunately I am at work
so it will be a few hours or so before I get home.

Thanks,
Jim
