Tvheadend

Hi,

I worked for several years with mythtv (3 analog PVR 350 / PVR 250) and mc2xml (cron).
Works fine.

Now I try to setup TVheadend with 1x TBS 6618 (DVB-C), 1x PVR 350 and 1x PVR 250.
Hardware already installed. Ok.

1.) How to import mc2xml ? (Data is already downloaded)
2.) How to map the channel list for the 3 adapters ?
or
3.) How can I map the channel list from DVB-C for both PVR 350/250 ?

Still read many msgs, but did not understand! :(
Maybe someone can help me?

Thx.
