[mythtv-users] PVR150 gives black screen with audio on channel change

Sat Apr 27 00:56:33 UTC 2013

I've never had this issue before but now I can no longer change channels
 on the PVR150. I can tune the first time but then when I change again I
get a black screen with audio. I'm using a change channel script and I know
the script changed the channel due to the change in audio. I have an
ATSC-110 as well and this can change OTA without issue. I tried changing to
from opengl to auto and I tried changing the hostname and I tried changing
the recording profile. Any suggestions?
