I have used VIX image and WinTV Nova DVB-T stick. DTT seems to work ok except for problems with HE-AAC. If I pause and timeshift HE-AAC works.

My main problem is that it seems like TS from USB tuner is not passed trough the common interface. Because of this I can only receive FTA on DTT. Norwegian DTT uses pairing (Conax) and only special Conax pairing common interface CAM's is working.

I had exactly the same problem in VU+DUO. Is there hardware limitations which prevents complete TS from DVB-T stick to be passed trough the common interface ?
