Need help with initial setup, EPG issues

[Remo]

I was afraid that changing the channel number, not the mapping, would screw up the tuning.

Thanks to both of you for the help. I'll work on it over the next day or so, hopefully no more problems.

The tuning is all established in the Device Setup setup when you do the scan; all the phyiscal channel stuff is there. Everything on the Channels screen pertains to how the channels appear in the EPG.
