Re: [PATCH] Add support for PCTV452E.

[Doychin Dokov <root@net1.cc>]

I also confirmed it works with s2-liplianin on Debian's 2.6.38-bpo2 
kernel without such problems.

Another thing I've tested is to compile the media_tree with the stb6100, 
but the problem persist, so it seems it's not related to the component 
that both devices share.

Any ideas what might be the reason for that, or at least where I should 
focus at searching?
