If you want PAL, why do you have -ofps 30000/1001 in the profile? -ofps

Thanks.  Didn't spot that. Changed it, and also changed the width to 720 to
height 576.

In terms of the container format, I have the of=mpeg=1. I thought that would
do it.

[ivtv]
tv=normid=10:norm=pal:device=/dev/video0:width=720:height=576
pvr=abitrate=192:vbitrate=2200000:vpeak=2600000:fmt=dvd:aspect=2:arate=32000
of=mpeg=1
mpegopts=format=dvd
ofps=25
ovc=copy=1
oac=copy=1
vf=harddup=1

Is it a conflict with the fmt=dvd setting in the pvr line?

Cheers
