[mythtv] AIR2PC Compiling Instructions

[Blammo [doh]]

I can confirm this is happening to me as well. File plays back with
chip-chiff-chiff (sorry, best impression) in mythfrontend, but mplayer
handles just fine.. (perhaps the 48k sample rate??)


Here's the mplayer -v - figured that would help:

[mythtv at frontend1 tv]$ mplayer -ao null -vo null -v
