Taking into account that you had 12GB free HDD space, and only 1GB free on the RAM drive, i suspect the RAM Drive to be the issue. Once timeshifting has started it will create a couple of files, and for HD TV they'll definitely grow bigger then 1GB in total (for all timeshift files together).okay, never could suspect that, i'm having about had about 12GB free disk space and freed up some more, now i have 19 GB free at C drive. I am running a RAM drive of 5GB with 1 GB free, but i'm guessing its about the C drive, right?
Easiest way is to monitor your RAM Drive when you start LiveTV and see what happens.
