[mythtv-users] "NVP: prebuffering pause" in mythfrontend.log

[Michael Tiller]

I wonder if perhaps we are overlooking something.  For example, I never
thought about it until now but I don't think my card is in an AGP slot.
Could that be the source of the issue (i.e. lack of AGP or proper AGP
config)?
