[mythtv-users] Blank Screen PVR-150 and LiveTV

[Hugues Belanger]

Hey All,

Well I've always been a big fan of MythTV, but I've yet to get it
working properly...! 

I've tried two different capture cards and I get the same problem now I
figure it must be something I just don't understand this is why I'm
begging for help:

Hardware:

MediaReady 5000
Via 1G CPU
VIA S3 Unichrome w/tvOut
PVR 150

Software:

Ubuntu 5.04
ivtv 0.38
mythtb 0.18.1

Here's what I know:

ivtv works, mplayer /dev/outputs video and ptune.pl allows me to change
channels. Not sure about the sound yet I have got that far.
I can play movies with mythvideo.

I configure mythtv-setup with the following

-capture card v4l

/dev/video0
/dev/dsp
/dev/vbi0
tuner 0

- Configured Video Source starchoice (zapt2it)

- Configured input Connnection
/dev/video0 --> Tuner0

When I start Livetv I just get a blanck screen with the following in my
mythbackend.log:
