Thanks

I added  second profile like this:

[ivtv2]
tv=normid=10:norm=pal:device=/dev/video0:width=720:height=576
pvr=abitrate=192:vbitrate=2200000:vpeak=2600000:aspect=2:arate=32000
of=mpeg=1
ofps=25
ovc=copy=1
oac=copy=1
vf=harddup=1

Then ran it:

greg at mediapc:~$ mencoder pvr:// -profile ivtv2 -of mpeg -o encode.mpg-endpos 20

I deleted quite a lot of the skipped frames.

Basically, I just want to record from the PVR-150 (on S-video) for  a set
amount of time. If I can record in format that make it easy to burn to DVD,
even better, but getting a decent recording would be great. CAT /dev/video0
> file.mpg works fine, but doesn't give me the options that I need (like
recording for a certain time , or hopefully at some point, being able to
record from the RF feed or the s-video depending on what I want to record.

Cheers
