Hi Terry,
I've finally updated the code on my epia to current cvs (I've been too busy 
doing the unichrome-pro drivers, that's my excuse anyway)

Anyhow I'm getting the same at the moment.
Changing to record TS reduces the problem slightly, but not much. Can  you 
confirm if you're recording PS or TS.

Also I only see this on some transmissions, are you sure that all old 
recordings are fine and all new recordings are broken?

Most transmissions are just fine but a specific example is Eastenders which 
exibits this problem (hey I don't watch it ok!). Could it be some sort of 
problem with the type of sound stream?

Regards,
