Since the summer I've been trying to optimize my mythtvbox with a good
ivtv driver that allows me to:
- record live TV shows
- play back recorded live tv shows
- play DVD's
- play homemade video's (mpeg2, WMV)
- play divx movies

The first two points work flawless since october( with good OSD
response), the last three points causes a lot of
issues/headaches/re-install etc.

We all do recognize the PVRx50 line of cards produce very nice TV-out
signals and mythtv is a wonderful tool to manage and centralize all
kinds of media (dvd, recorded shows, divx, pictures, mp3). But as soon
as you want to use the framebuffer of the PVRx50 card to play your
media (DVD, divx, home-made video's) the mailing list is full of
problems around tearing, a/v sync isues, framedrops,  etc.

While recently there have been a lot of works to optimize ivtv's
framebuffer working and creating plugin's for the mediaplayers as xine
and mplayer, there is still a fundamental problem in combination with
mythtv. X is using the frame-buffer on the pvr-x50 output and your
media-player (mplayer/xine) when playing via the optimized
plug-ins/patches.

Has anyone an idea if we could tweak X and mythtv that when you start
playing a movie from mythvideo you would do something like:

stop/freeze_x_on_pvr_350_tv_output ; mplayer -v ivtvosd -fs %s ;
unpause_x_on_pvr_350_tv_output

As such only one program at the time is using the PVRx50 frambuffer,
either its the X or the mediaplayer (mplayer/xine).

Any-one thoughts comments

Bytes,
Stefan
