I am really really really surprised this is still a problem in ivtv.
EVERY upgrade I have done on ivtv needs to be hacked again. Is this a
PVR-150 only problem and they don't want to fix it????
Here is a link to the source code hack....
3/4 of the way down it talks about editing ivtv-streams.c

Good luck!
