HD playback 25 fps + Video-out

[isotron]

Hey, ihr könnt gerne in deutsch antworten, habe den text nur für andere Foren in englisch verfasst.

I think nobody can help me really, but i will complain what i am tested, and maybe someone has a solution.
The task: to playback 30sec spot with a res. of 1920x1080 in 25fps and view it on an JCV/Sony/etc Class1 Monitor.


The System: 8 core MAC 16GB RAM with Aja Xena 2k and Final Cut Pro.
SAN Storage: 260 MB/s -> DPXsequenz 8MB pro File = 200MB/s ----> DPX to QT ref -----> all is fine!

The System: same storage...
8 Core PC Vista x64 16G RAM with Aja Xena 2k and.....
Combustion: without chaching, without Xena View - 12 fps
without caching, with Xena View - 6-10 fps
with caching , with/without Xena View - 10fps/25fps.
Fusion x32: without caching, with/without Xena View - 19 fps.
with caching , with/without Xena View - 23fps/25fps.
Fusion x64: "" - 19fps.
"" - 21fps/25fps.
Sony Vega : without caching - never open dpx in vegas ;)
with ram preview - 25fps but not constantly :/

so what should i do? i finish my work with the client on the PC with Fusion.... and cannot switch to FC for a look.... and Generation... hmmm... playback is great...but with Aja/deckling support too?

What do you use for this task?!
