I have latest ATRPMS - I experienced the version with the MMX issue and
that caused stuttering on every channel. I have the latest MythTV
release on ATRPMS as of yesterday. (I took the risk and ran yum update
yesterday in the hopes it would be resolved.)
Could a very strong signal cause this type of problem? Ie:
Overpowering things? Both ABC and FOX are coming in at 96% signal
strength according to dtvsignal. A few other channels come in this
strong... but they are fine.
I forgot to mention the machine with the stuttering is a frontend only.
My first email should have said the OTA ATSC cards are on a backend
server. I guess I was a little tired when I wrote the first message.
Should I check the logs on the backend? (Which is lucky to see 10% CPU
utilization even when recording three HD shows simultaneously.) Or
should I look at the frontend? (In which case where would I look for
log entries on a frontend only?)
Thanks for your help with this.
