Re: video from USB DVB-T get damaged after some time

[kapetr@mizera.cz]

Hello,

I have test FW version 12.10.04.1
(FYI dmesg changes follows)

The problem without change.

I did want to test the DVB-T stick under Windows XP, but in VirtualBox 
works the tuner not at all - I get just jerky sound, no video.
But there is older driver (12.7.6.11) - but don't thing the problem is 
there - rather in VBOX.
And no free partition to test.

Regards.

kapetr
