I use TBS6280 (dual tuner, pci-e) from Turbosight in dvb-t mode (no dvb-t2
signal here): good card, not expensive and great technical support. Newer
model is TBS 6281 :
I have the TBS6281 and have found that the drivers from TBS are a pain to get co-existing at the same time with other kernel DVB drivers (e.g. my Prof USB DVB-S2 device) and need re-installing after every kernel update. Also, I think that the open source drivers do not support DVB-T2.
However, on the positive side once the driver is installed, the card is stable.
