Media Center (Vista) and DXVA plus subtitles

For many people with an (not so powerful) HTPC and using a LCD TV (Full HD-or HD Ready)as a display, it would be very useful to play all kinds of videos with less CPU usage and , what is very important, the player used shoud be easy remoteable.
Media Center is such a player. Of course you can get DXVA in MC with various set-ups , but try this one too:
Download latest FFDShow MPEG-4 Video Decoder (2010-01-28 Rev3233) from here:
http://sourceforge.net/projects/ffdshow-tryout
During instalation chose to enable DXVA (optional "no compatibility check" option). If you want to use the internal subtitle filter(for BD Rips +subs- H264-mkv or m2ts) of that decoder you have to enable postprocessing. For DXVA to work ,external subtitle filters should not load(ex. VS filter).
Choose font size (40-50).
Now load the file with Media Center .
For me ( Intel E1600 ,an HD3650 ,2Gb Ram,Vista 32bit, ATI 10.1 drivers) this set up works very well.
Any feedback would be highly apreciated.

Just how do you get subtitles here using DXVA without MPC-HC's auto-load subtitles?

ffdshow h264 decoder has it's own subtitle renderer.
I was refering to Media Center. In MPC-HC do not tick "auto-load subtitles" in Playback section if you really want to use that option(ffdshow subtitles). Better stick with MPC-HC 's own subtitle renderer ,though.

I'm not seeing this. Could you please post up a link to a screenshot of this setting?

I know ffdshow Video Decoder has internal subtitle support, but ffdshow DXVA Video Decoder only seems to have a setting for Hardware acceleration and nothing else.

You have to enable postprocessing to use that feature...I guess that means it would use overlay output(?).

What version are you using again?

I've got ffdshow tryouts 3233 and there is no post-processing nor any subtitles tab.

You guessed wrong. Here is the official ffdshow site:

Very Sorry! Links were messed up! Yes I'm using that one! It seems that first builds with DXVA(from 3190 ,I guess) ,haven't indeed the subtitles options. I will edit the link above.

Ignore number of reference frames + surface overlay + Subtitles is a very bad combination for Intel graphics card.

There is corruption in subtitles where there is video corruption without subtitles (same corruption experienced by MPC-HC's internal DXVA filter in compatibility mode. Of course without compatibility mode, there is no DXVA. MS DTV-DVD filter can accelerate those files that require compatibility mode with [MPC-HC's internal DXVA filter/ffdshow DXVA] but without any corruption, but no internal subtitles -> have to use MPC-HC's auto-load subtitles).

I guess you're on W7 OS( because you have MS DTV-DVD filter and a Intel card) ,try to see what happens in Media Center ,but I assume you have to find a way for MS decoder not to load there...but ffdshow decoder instead.
And try to use files(H264) with a lower number of reframes(<10-12). Videos with more than 12-14 ref. give me coruption too, no matter which DXVA decoder I 'm using

I can't, as that is how my files are encoded. In particular, I have one file that is 12 ref frames that I always check for arifacts because I know where a couple are from watching it a lot. The MS decoder will eat it all up (with no artifacts - partial acceleration?).
