Have they been using the supplied Windows software, or the Linux software? The Windows software probably doesn't allow you to fine-tune the tuning parameters. > There seems to be a few potential/actual problems: > 1.

The L64781 COFDM demodulator used in the Nova-t cards supports 6, 7 and 8 MHz channels. From looking at the specifications, it seems to support all conceivable forms of DVB-T broadcasts, so that shouldn't be a problem. The Linux driver allows applications to set all these paramaters. > If I understand correctly the nova and the tecnotrends DVB-T cars are > essentially the same? > > I would guess that the specifications for the tuner chips used on these > cards would answer these questions.

I don't know about the actual tuner, but the "COFDM Demodulator" in both cards is the L64781 which was co-developed by LSI Logic and BBC Research and Development. A search at www.lsilogic.com will give you information on this chip, but I couldn't find the actual datasheet (but I downloaded it from there last year).
