I've had some issues too but it turned out that was because the automatic mythfilldatabase was disabled, I moved everything to a new backend and somehow that got missed!

Yep, that's the latest, I'm running 0.5.59 compiled from the xmltv site.

There's all sorts of potential for timezone related grief in that. Myth works on local time and it's been deemed "too much work" to re-work everything to use utc timezones and offsets so with that added in there is every chance something has got mangled, offset twice somewhere.

I'd be inclined to create a cron job to clean up and start again twice a year an hour or two after the DST/BST change dates. :-)

What extra does the BlebTV feed get you?
