I have an Acer Revo 3610 (Win 7 x64, 4 gb RAM) that I'm using as HTPC (connected to Phillips TV via HDMI).

 I've upgraded from MC15 to 16 to be able to successfully view Blu-ray discs (using DVDFab.)

I can do this except for the terrible stuttering/latency of audio. I have checked related threads in the forum, tried variations within WASAPI, Direct Sound, even Wave Out in order to get the movie to play smoothly or without the audio stammering or being out of sync. I do find that RO advanced with HDMI bit-streaming appears to be the least offensive, but nothing I've tried gives a good performance.  I think that something I tweaked in MC15 was carried over . . . can anyone recommend the "default" settings for Audio/Video playback so that I can at least start from scratch?

Welcome.   Could you run the benchmark feature under Help and post the results?

Start with Red October Standard and make no changes to it until you solve this problem.

Try changing the Audio setting under Video.

I would recommend offloading as many CPU-heavy tasks as possible. Try installing LAV CUVID: http://forum.doom9.org/showthread.php?t=160290 and set it as an additional filter in RO standard + additional filters. Bitstreaming is also probably a good idea too.

That's a very low power machine.  Red October Std might work if nothing else is going on in the background, but ROHQ won't work.

Agreed.

You'll probably find that the stutter coincides with your CPU maxing out.

You need to offload the video to your GPU, which RO doesn't do.
