Well it looks like the DVB-S date/time is wrong to me. The UTC time for 
news at 6 pm should be 2012mmdd060000 because we're 12 hours ahead of 
UTC. The MHEG UTC time 2012mmdd060000 +1200 equals 6 pm local. Are you 
using a time offset of 12 hrs in the myth EPG config or just the auto 
setting with no offset?

I have a minor tweak ready to upload which just produces UTC times with 
no offset. Maybe that will help.
