[mythtvnz] Freeview|HD buffers and Audio Sync

[Steven Ellis]

I've been discussing the buffer size issues Jean-Yves has been
investigating with some of the freeview techs they passed me the following
article as a reference.

Does anyone know how often MythTV refers back to the PCR to maintain a/v
sync?

Also what is the largest gap between an audio frame and its associated
video frame that has been seen for the freeview|HD broadcasts?

Their current statement is we shouldn't be seeing an offset of greater
than 70ms which doesn't sound right.
