[mythtv-users] Initial Channel in LiveTv, Recording is corrupted

[Milan Siebenbürger]

Hello,

I bought new Hauppauge DVR 1300 TV card, and trying to set up myth tv to
watch and recording tv. I have to use analog channels (for now) and I have
this problem :

When I start live tv - there is no channel tuned, just scrumbled screen.
When I manually change channel, everything works fine - from this moment is
mythtv excelent.

It isn't as big problem in live tv, but same problem is with recording -
everything what I want to record is scrumbled again (mythtv doesn't tune
right channel?).

There are many weird messages in backend and frontend logs, but searching on
the Internet gives me no result. I've tried different version of mythtv
(0.21, 022 - from gentoo portage) and kernel sources (2.6.30, 2.6.31) - with
same result everytime.

backend.log: from A1-> scrubled screen, from A2 (manually changed channel)
is everything ok
