fixed that (and no, sorry, I didn't compile test it, I have to focus a bit on
a biotechnology exam, maybe later).

ok, changed it. but I am not sure whether the last two hunks are ok. Should
we error out like this or just let the negative value be assigned to
ps3av->ps3av_mode? If not, is there more cleanup required?

No problem.

Make id signed so a negative id will get noticed. Error out if
ps3av_auto_videomode() fails.
