 The 'xmltvid' field is used to identify this channel to the listings

+The 'tmoffset' field is used to apply an offset (in seconds) from the listings
+provided by the provider to a new time in the MythTV program guide database.
+This is very handy when the listings provider has listings which are offset
+by a few hours on individual channels with the rest of them being correct.

 The 'recpriority' field is used tell the scheduler from which of two 
 otherwise equivalent programs on two different channels should be 
 prefered, a higher number means this channel is more preferred.
