just so maybe we can compare, I haven't had a crash for a while, and I use MC only for TV. I record a ton of TV, and haven't really had a problem.
My main server is an Intel i3 Haswell (refresh), 8 GB of RAM, running Win 8.1 x64.
My client (used only to watch live TV, or recorded TV) is AMD based with an AMD HD6570 GPU, 8 GB of RAM, also running Win 8.1 x64.
On both, I use the built in Windows AntiVirus.
I use 2 HDHomeRuns (OTA tuner), and 1 HDHomeRun Prime tuner.
Oh, I am recording to a USB3 external drive...thought it might cause issues, but so far, no issues with that either.
