Freeze when switching to dvb-t

Hi there,

Sometimes (about 1 in 20 times on average), when I switch from a satellite channel to a DVB-t channel on my Vu Duo, the whole box freezes up. This is using a Sony PlayTV usb tuner.

I can see the following in /var/log/messages

Code:

Any info on this would be appreciated. Thanks a million.

Ask on Vix Board. This is the Black Hole Team Board. If you need support for your problem, first install BH image and retry with your DVB-T USB tuner.
