[mythtv-users] Change Channel After Some Hours causes Stop Start AV Cycling - MythBuntu 8.04.1 - Analogue PVRs

[Tortise]

Hi

I have run up two boxes using the above OS/package, one using a PVR-150 and the second a PVR-350.  Both AMD2400's with >2G RAM, NVIDIA 4 and 5 AGP series cards trialled.  mythfilldatabse has not yet run successfully, I am awaiting a DVB-S card and pulling the EPG off that stream, at least for most of it, there will be residual on UHF somewhere.  Both Boxes front/back configs all on the same HDD, one is a new 500G IDE. 

I find the CPU runs about 20% on live TV.

When I leave it running a few hours, then change channels, they jerk and stop and start - about half a second running AV, then stops half a second - and continues like this.  CPU Jumps to 95%.  Happens on both boxes!  Exiting Myth and starting again fixes it, of course I lose the buffer also - this option would preferably be avoided!

Is this a known problem?

I do not know the appropriate search terms / description for this behaviour to find the answer to this, it seems likely there is an answer?

Many thanks in advance

David
