Maybe I have time this week to look at your sources too... But livetv is
still broken with this patch, or not??? I think we should look that
livetv also starts recording to two files when a new programm is started
while watching live tv. but then you should stay watching the old file,
as long as your overlap time in the db is set. after that livetv
switches you to the new one. i haven't yet got a look to the livetv
code, because i don't use it, but i'm looking how difficult this would
get within next week.
maybe also we should make in configurable if the recording to multiple
files is used or not, because maybe not everyone likes it..
