[linux-dvb] Signal strength / quality

[Michael K]

Hi!

I recently added a Terratec Cinergy 1200 DVB-C to my MythTV-box.

My recordings seems to be okay, but one of the channels has delay in the
audio stream, and XBMC's mplayer aborts when the recording has played
for some time. Could this be caused by a poor signal?

from dvbsnoop -s signal:

I haven't been able to find much information regarding signal strength /
quality so any feedback would be welcome.
