Well, It still freezes within 3-5 minutes of starting a background
transcode. I can reproduce it _every_time. I've also added a second 6
GB hard drive that only has the buffer
I also crashed the frontend by pausing live TV and then fast forwarding
back up to current time - when I did, the frontend started using 100%
cpu and froze. After that, the backend wouldn't respond to a web status
request either and both backend and frontend had to be killed and restarted.
Does ANYONE actually have this working on a PC using (not an XBox)
using software transcoders without having freeze problems? What
hardware / distro do you use?
