Hi all,
There have been various bug reports lately regarding freezing of the PC
when starting a capture or when changing channels.
I've been stress testing this yesterday and today and I believe I have
found and fixed the problem. And as an additional bonus I believe that

Attached are two new patches: it turned out that an extra wait was

Hi all,

Hmm, it turns out that I generated the patch for ivtv-0.10.x against an
