Help!

Got a venton unibox hd2 (vix), and on many channels, including some free to air such as 5HD I am either getting 'tune failed' or 'Timeshift not possible', then 'tune failed'.

I am still getting some subscription channels, but not others (most). Not had this before (everything was working).

Done full reboot, run autob, checked connections etc.

Done a scan and get nearly 700 channels.

Appreciate any thoughts on what the problem may be.

Thanks!
