Hi Tim,
My only advice would be to submit a ticket as nobody directly from Centova seems to be coming to the forums right now.
Sc_trans V2 does work, I can assure you of that as I have had it working very well. I have also run into errors like you have though at times, which sometimes were down to the media that was uploaded.
On the latest install I have run though (With Debian Squeeze 32 Bit) it seems to work ok.
The only thing I can't get to function is the Windows Media services.
If you don't get any help from Centova, then I could have a look for you when I get some free time (Things are a bit hectic here right now)
