Performance tweaks for video playback startup

I recently rebuilt my Win7 64bit PC which host sageTV server; as well as my primary sageTV client.

Im curious if I've missed any performance tuning settings which would help reduce lag when starting videos as much as possible (considering I already have abundant RAM and use an SSD). Currently, the maximum time it takes to start a video is only 1-2 seconds.

I only know of three settings which people have suggested on the forums to help performance in general:
3. Javaheapsize=1024
4. NumBuffers=0x00000100
5. BufferSize=0x00020000

I've also increased min_bandwidth_for_no_transcode=19500000 since all my clients have >20mbps sustained data rate; including placeshifter.

OS Prefetch/superfetch are at their defaults to optimize boot and application startup.

Anything else I can try?
Upgraded to Comcast X1 + Netflix/Amazon Video streaming
