Sorry about the top posting, I forget most of the mail clients just do it.
I am using v30 with latest updates. After doing a rescan, I can tune to the
channels but lost all guide data from schedules direct. When watching
mythfilldatabase I see the error as no channels found for grabber. Looks
like I need to go to xmltvids vs the direct way but good grief does it look
complicated to move over, especially when you don't want all the channels,
I have it on schedules direct with just the channels I want but not sure
how to pull that over vs going one at a time via the command line update.

Anyone has an easy way to port lineups over and save me some time would be
welcome, seems like a total pain right now.
