[mythtv-users] DVB-S (Nexus-S) channel changing / DB mixup?

Hi,

could someone please give me a hand on this one - I have been on to it
for some time now... x-I

I am using the latest DVB cvs build and the latest mythtv cvs build on a
RH9.

I can set into the mythconverg database such channels that the NEXUS-S
card (videodevice #0) is able to tune to. The catch is that the channel
must be set as startchan in the cardinput table.

I can select the numeric channel that is the startchan, but if I enter
any other channel number, the display freezes, the new channel# fades a
little bit, and then nothing happens.

Now, some questions:

1) does mythtv DVB functionality currently work with the latest DVB cvs
drivers? What is the recommended driver package to install for best
results? (The current does work with mplayer though).

2) Can somebody please have a look at the enclosed backend/frontend
outputs and the database output (from mysqlcc). Is the database just
mixed up, and if so, how to correct?

	QTime::fromString: Parameter out of range. ??

3) Does mythtv support live TV viewing with a setup where one card is
DVB-T (Nova-T) and the other is DVB-S (Nexus-S) ? I think I saw one
comment stating it is not possible (yet)?

4) Having both cards mentioned above in the system, the nexus being card
0 and the nova being card 1, how could I command the frontend to tune to
channel 1 of the nova card, rather than channel x of nexus card?

5) as a last thing, has anybody available description on the tables of
the database, their fields, and relationship diagram? That would
probably help others as well to get grip on how to configure mythtv.
 
Thanks for all the help!

Petri
