Video frame buffering failed too many times

[Stefan Pappalardo]

While watching tv video freezes and falls back to main menu.

I'm using a combination of front- and backend on one mythbuntu-box.

Here you can see what mythfrontend wrote to its logfile:

UpgradeStatus: Upgraded to precise on 2012-05-17 (10 days ago)

[Launchpad Janitor (janitor)]

Status changed to 'Confirmed' because the bug affects multiple users.

i have a seperate frontend that runs 0.27 atm. when i ran 0.25 on BE and FE they both worked fine. i could watch live TV on both of them. upgrading to 0.26 broke it. live tv still works fine on the BE but the FE can't watch it anymore. after 2 seconds i get above messages. i upgraded to 0.27 hoping the dev version would have it fixed. but lifeTV still works on the BE, the frontend is still broken. i run ubuntu 12.04LTS on both of them.

[Herco van Brug (hercovanbrug)]

spoke too soon. watching liveTV on the backend works fine until i switch channels. it then waits exact the amount of seconds i entered in mythtv-setup before failing with the error from this topic.
