I've used nothing but the xmltv feeds since I set up mythtv back in the dark 
ages. Yet, I /still/ find that my system sometimes forgets about programs that I 
/know/ have been recorded in the past - and which may indeed still be on disk.

The only way to deal with these is to override with 'never record', which makes 
a fake entry in the db saying that the program has, in fact already been recorded.

If you use 'Subtitles then Description' and 'New episodes only' you'll find that 
you don't get too many duplicate matches, even for Grand Designs, which I also 
record. It doesn't take long in mythweb to zap the rest.
