I just ran mythfilldatabase and noticed some wierd scheduling conflicts.
Here is a part of "mythbackend --printsched"

Take a look at the 28:th, xena conflicts with first wave and andromeda, but
why wasn't firstwave and andromeda scheduled to record on the second card,
the dvb card, like it did on the 21:th ?
Channel 4 exists on both of my cards, the analog bttv and the dvb-c card,
the dvb-c card has higer priority than the analog one.

Coud this be caused by the fact that some of the schedules was set from
mythweb a long time ago, like a year or so?

Have I missed somehting about the scheduler? Or setup something wrong?
