[mythtv-users] Video playback speed very fast

[John Watson]

Hello all,

I have been using mythtv on a Mythbuntu HP Microserver for a few years
now. Just recently when I tried to watch live TV or recorded video, I
noticed the video looked like it was being fast-forwarded and there is
no sound.

It was working perfectly for many months but something has happened
recently to change all this.

I have logged into the server and updated Mythbuntu (including a
"sudo apt-get dist-upgrade"). My local Arch Linux PC has also been
updated but still the video plays too fast. I can slow it down and speed
it up using U and J but normal speed is the fastest!

I have tried "mythfrontend -v --loglevel debug --logpath
/home/john/mythtv-logs --geometry 1900x1060" and have obtained a large
log file. There doesn't seem to be much to go on:

I have Mythling installed on my Android device and it can play the
videos back correctly. This makes me think it is to do with my Linux PC
frontend??

Can anyone offer any suggestions? Thanks.
