-There's not a traditional ringbuffer in myth since the livetv switch was
made (.19?)
-Even when there was a ringbuffer, it was never a bottleneck AFAIK.
-Again, back when there was a ringbuffer I believe its default was somewhere
in the 1-4gb size.

What problem is this idea trying to solve?  Having 64Gb of ram might go
really well if you're doing a LOT of simultanious HD recording if you tune
the kernel to be REALLY agressive with its disk caching, but otherwise it
woudln't do anything whatsoever.
