[mythtv] eit scan breaks liveTV

Sat Sep 24 12:35:37 UTC 2011

Hello,

Sorry for my poor english.

I use master/trunk version of mythtv, I know it's not ready for enduser but 
I like some of the new features.

But since v0.25pre-3370-g7fa4d4e I have trouble with liveTV. I start LiveTV 
on /dev/dvb/adapter5/frontend0 and after a few minutes it's stopped. I 
found:

in log of mythbackend (started with -v none,channel,chanscan,dvbcam) at same 
time. After set eti_scan on this capturecard to 0 it seem to work like it 
should.

I've not open a ticket yet, because I've make to many errors at my last 
attempt to open one.

Kind regards,
Sebastian
