[linux-dvb] Wrong data from Hauppauge NOVA

[Ralf Bauer <RBauer@quark.de>]

My VDR machine contains 2 DVB-s cards, one DVB-S card with old tuner and one
NOVA with new tuner.

I noticed that some channels (for example SAT1, WDR3) cannot be recorded
with the NOVA card, but show no problems when I record the same channel with
the DVB-S card with the old tuner.

My first idea was a tuning problem with the new tuner, but when I recorded
Pro7 which is on the same transponder as SAT1, it worked fine.

I looked in the messages file and found the following lines:

I used Klaus' xlist.c to look at the data and found the following:

Obviously VDR is right when complaining about the IDs.
When I record SAT1 with the DVB-S card (not the NOVA), the data looks OK:

A recording of Pro7 with the NOVA card on the same transponder looks also
OK:

Where do these wrong IDs come from?
