The xmltvid is not used at all when you use EIT. The xmltvid is used
to identify the channels for external guide data such as that from
Schedules Direct.

EIT /EPGdata is per videosource; for example, EIT/EPG data for a DVB-C
videosource is received by a DVB-C tuner connected to that
videosource. The same EPG can be used by other tuners connected to
that videosource but not by tuners connected to another videosource.

The only way that I know to get the EIT EPG data from the DVB-S to the
DVB-C videosource is with a SQL script that you can run in a cron job.
This is not done automatically by mythtv.

If you have identical guide data for the DVB-S and the  DVB-C
videosources , for instance with a script or from Schedules Direct,
then you can give the DVB-S channels and the DVB-C channels the same
channel number and the same callsign and the recordings are then
scheduled according to the priority defined in the "Input connections"
/ Ïnteractions between inputs" window of mythtv-setup.

If you give equivalent DVB-C and DVB-S channels different channel
numbers then they will appear as separate channels in the guide, but
for scheduling the channel number is not used, only callsign and
starttime of the program.

In your situation, I would:
- Use different callsigns and different channel numbers for the DVB-C
and the DVB-S channels.You can change them after scanning with the
Channel Editor page of mythtv-setup.
- Use EIT on both DVB-S and DVB-C.
This way you have complete control on what you want to record on which tuner.

Groetjes,
Klaas.
