In particular read the parts around this quote: "Especially german users who like TVToday will like WebGrab+Plus, because - as the german users know - Webepg became
very unreliable until not working any more for TVToday...
Background: TVToday has put a lot of advertisements in it´s site and Webepg seems not to be able to handle that."
I'm facing the same problems since a couple of days, too. The logfiles don't show any errors, so it is likely that TV Info modified the data in some way.
It seems as some channels still work properly though, like RTL for example. Could of course be a coincidence...
