I am on the list, but our corporate spam checker ate the
message :(

The original vlc (eg 0.8.6) has a copy of videodev2.h in the
modules/access/ directory.  If I check in configure for the
system copy of videodev2.h then:

1) I have to make sure that pvr.c does not use the old
   videodev2.h in modules/access/ (easy: just delete that

2) A vlc built on an older machine with an older 
   /usr/include/linux/videodev2.h would not be able to
   compile in features that are needed on a newer kernel
   / ivtvdriver.  The build would have to be on a new machine.

3) In my build environment (Fedora Core 5 with 2.6.20-1.2300.fc5)
   trying to build my patched pvr.c using the system
   /usr/include/linux/videodev2.h does not work because
   it is too old a version of the file!

Unless there is a way around this, I think we're stuck
with using a local copy of videodev2.h :(

Ok, I'm happy to make those cosmetic changes.  I would
justify my preference for "++p_controls->count;" to
your "p_controls->count++;" because I usually write in
C++ and pre-increment is more efficient there!

Yes please!
