Yeah, that's a really bad problem that you have due to the fact that
your broadcasters are sending out garbage data...
If only there were some way you could pay some small amount of
money--say, maybe, $0.05/day--and get the same data that TiVo users pay
$15/mo to get...
(Remember, also, that http://schedulesdirect.org/ offers a 7-day free
trial, so if you're not sure, you can try it out. Also, note that
duplicate matching with US EIT is largely useless as each channel will
give different descriptions and different amounts of info and there
won't be "authoritative" programid's to use instead. However, duplicate
matching with SD data is virtually perfect because a single provider
provides . The only time it fails for me is when the broadcaster fails
to provide info on which episode is showing (so you get a "generic"
episode that Myth records, anyway, just in case).)

Use open-on-demand for the digital device. You may also need to use
passive EIT (which has its downsides), but I'll let someone who actually
knows about EIT tell you more.
