[mythtv-users] frontend error messages prebuffer wait timed out

[Phil Wild]

Hello mythtv users.

My mythtv frontend is hanging every now and again when watching live tv. I
would expect it to hang within a few hours of being turned on.

I am trying to track down why. This is a new install using mythbuntu 8.10

I see a NVP: Prebuffer wait timed out 10 times.

around the time when it happens but I also see this message when switching
on live TV

Does anyone have any ideas?
