I'm working lately on DVB-S support and you surely noticed the delay in the releases. There is the saying "Never rewrite your code!" which I generally agree to, but new hot ideas make me focus on the new MegaEPG version 2 engine. I believe the DVB support will solve a lot of EPG problems. Be patient, it will be worth the waiting.
I'm taking the opportunity to mention the Vista TV Pack 2008 (aka Fiji). The MegaEPG does not support it yet. Microsoft has completely changed the EPG access and schema in this product so please don't install it if you continue using MegaEPG.
The rest is for Israeli friends: on October 5, 2008 Israel moves to the standard time (DST off, one hour back). A special attention is required. Ensure you have the DST flag off in the operating system (do not correct the clock itself!), ensure your clock is correct at morning October 5th and the EPG is not shifted. Re-run the MegaEPG if required, then update the guide in your PVR application. I wish you happy new year, much of health, wealth and only accurate EPG in the new year! :-).
