With my RPi, I don't want to be continually writing a timeshift file to either of my Flash devices (SD card or USB) as they're prone to wear, so what I'd like to be able to do is use a small RAM buffer instead.
I generally never skip back more than 1min and only have SD Freeview. I'm not sure exactly how much space that would require for 1min but say it's around 50MB, I think I could spare that on my 512MB RPi (using 128MB for GPU) as much of the RAM is only used for buffers at the moment. Ideally I suppose it would only reserve and use the RAM for the timeshift whilst watching TV and release it back to be used for other purposes when TV is stopped.
