I am :-(

I've just transcode a couple of programs I recorded recently, one was 
complete garbage, the other transcoded fine.
Im pretty sure both these recordsing were made using svn 8630 snapshot.

The good program was from Channel 4  and the corrupt one was on ITV2 
both early in the morning on 22 Jan. Im in the UK

I have not changed any transcode/MPEG settings.

My set up is 3 Avermedia 771 DVB-T cards on a amd 64 3200 box. with a 
number of remote client pc's


Guess its time to upgrade to the latest svn and see if its still 
happening, especially on new recordings.
