Hi all,

Having done some further work on this I have now got what I believe to be the optimal codec settings for my system.
Hope this helps someone in setting up a similar system for HD in the future!

An initial key lesson for me was around using the graph accessed using 'Shift + 1' to determine the level of dropped frames when using each h264 codec when running either local (1080p) or streaming (720p) HD content. This also pointed out to me that a major source of the stuttering was the TightVNC connection I had open to control the media centre whilst this was all going on (what a muppet!).

Having now run the setup for a while examining the graphs there is a clear winner in terms of quality and level of dropped frames. The LAV filters with DXVA2 Native selected is by far and away top in quality and speed for both local and streaming media.

1) LAV Codec with DXVA2 Native Selected and software deinterlacing deselected (deinterlacing settings not extensively tested)
No dropped frames in local media, very good.
Some micro-stutter streamed media, takes time to settle down. ~900-950 dropped frames for 6000 drawn.
2) Cyberlink PowerDVD 12 with DXVA enabled
Very good for local 1080p file, 1 dropped frame in 5 minutes and no stutter.
Some micro-stutter noticable in streamed media, ~1100 dropped frames for 6000 drawn. Quality appears lower than LAV?
3) ffdshow DXVA enabled
Stutter in both local and streamed media. Didn't do a dropped frames check as wasn't ever going to be acceptable.

I guess the key thing here is that a system like this is perfectly accceptable for local 1080p files. However, with streamed media it is very close to its limit but watchable for now until I upgrade in the future (Intel NUC anyone? ).

Hope this gives some interesting and helpful information for others on here.

Cheers,
Phil
