[MPlayer-users] mplayer pvr:// errors

[Steve Dibb]

So, once upon a time[1] I actually had mplayer pvr:// support working 
just fine.  I've started testing it again, and with recent kernel 
(2.6.23.1) and recent SVN of MPlayer (25056), it's not working at all.

AFAICT, it's not an issue with the cmdline opts I'm passing, but you 
never know.

I can verify that the IVTV drivers are indeed working, since "cat 
/dev/video0 | mplayer -" works just fine.  After doing any attempts at 
playback with mplayer, it will lock up though (cat no longer works), and 
I have to remove and reload the IVTV driver.

Looks to me like it is dying somewhere in the demuxing.  The command 
exits fine, but of course nothing plays.
