Hi folks,
I tried a new SVN version (8088) and hoped that all the live TV changes
would improve the unreliable channel tuning I was fighting with before.
However, it doesn't.
The symtoms are the following: sometimes when tuning to a channel, the
frontend gives output like this:

It will hang now, pressing escape doesn't work. I have to restart the
frontend. After this, tuning to the same channel ususally works.
This occures with several channels on different transports at a random
pattern. Recordings doesn't seem to be affected, only live TV, at least
I can not remeber of any recent failed recordings.
My card is an old WinTV Nova-T PCI, the kernel is a plain 2.6.14-rc5.
The problem also occured with the SVN versions before the live TV
changes and with older kernel versions. I use the DVB-T broadcasted in
Berlin, Germany.
Are there any things I should try? What verbosity options should I
enable to give further information from the log files?

Tino
