I didn't find that thread in the archive (?!?! what happened? I've got censured? I've been rude without knowing it? If yes, I'm sorry) so I've put my original email near the end of this one.

I wrote that part of secttion code :), but I wasn't active on
list at that time.
My idea was to capture anything in order to fight certain packet
loss from some boundary conditions and I didn't know I would break
anything if I feed some initial garbage from the just tuned stream

I didn't have such problem with my setup (haupaugge NOVA-S and a home soft) and I can understand that my patch may have some side effects unknown to me. But the bug is here and it is still not patched.

I don't think this has anything to do with buffer overflows?!
those could be from av7110. Aren't they using different 
demux in firmware?

Should be no problem I think it should be applied to CVS.
I can try this code myself but from first looking
it should be good
