I'm watching livetv with mythbuntu 10.04 and have the latest updates installed.

But after a few minutes/seconds live tv stutters.

Here is my mythfrontend log file.

Just a quick update.

I.m using 10.04 64 bit and i haven been searching on the internet for sometime and found things like change the audio input (now set to /dev/dsp).

(When i change to Alsa: analog i don't hear a thing)..

I get something similar but I haven't sorted out the cause yet. See logs below.

LiveTV either freezes until an error message "Video frame buffer failed too many times" and closes or stalls for up to 20seconds seconds and then recovers.

I am getting an error "Video frame buffer failed too many times" occasionally since upgrading to mythbuntu 10.04 (mythtv 0.23). The error occurs when watching livetv, livetv freezes and after some time the livetv screen closes and a pop up with the error is shown. Clicking OK returns to the mythfrontend menu. Selected log entries are included below. Anyone with any ideas of how to solve this.

I'm watching livetv with mythbuntu 10.04 and have the latest updates installed.

But after a few minutes/seconds live tv stutters.

Here is my mythfrontend log file.



Can someone please help me.


I had the same problems with prebuffer pauses and audio buffer underruns.
In my case, the problem seems to be the wireless network card.
In the syslog i have found the entry :

phy0: unsupported jumbo

at the same time my system crashed.

I tracked the problem by using top, showing the CPU load.


topphy0 caused high cpu load and my frontend/backend crashed.
I deactivated the network.
I am right now testing for more than 5 hours watching live tv and until now
had no crash.
Maybe you have the same problem or another hardware cause high cpu load.

have you tried using the Mythbuntu Autobuilds and ugrading to .23.1?

Yes and the problem still remained.

That's why I thought I'd try moving to 0.24 but nothing changed

apparently there was was a fix that went into 0.24 but I haven't found it.

Thanks.

:-)
