I used the following scan file to scan for HDTV signals

T 554000000 8MHz 2/3 1/2  QPSK  8k 1/32 NONE

It is not working anymore now, but instead I use

T 554000000 8MHz 2/3 1/2  QAM_64 8k 1/32 NONE
(which btw does not give any more the full list)

I'm not sure what is the problem, maybe is the card.

Anyway, those are the channels I could scan

You need to manually set the video pid since it is not MPEG2 but H262
and scan does not like it. If you read the mailing list in the last
4/5 months you should find somehting on how to play those signals.
MPlayer is fooled by the fact that the video is not MPEG2 but H262
(which it does not expects), there was a patch to manually specify the
codec.
