Windows 7 and ffdshow (directshow problem?)

[hechacker1]

I'm giving Windows 7 x64 a try. Overall it's much better than Vista Sp1 (on my hardware).

But there is one problem. directshow and vmr9 seem to be buggy/broken. SageTV only can play using the "Default" decoder, otherwise I get an error message about not being able to render the video.

According to DirectShow Filter Manager 0.5, Microsoft DTV-DVD Audio and Video decoder are with "Unknown Merit". I have installed ffdshow (32bit and 64bit) and set it's merit to "Highest." In Vista x64 sp1 this all worked fine.

According to Graph Edit, when I render a video file (with the default renderer) the "Microsoft DTV-DVD Video" filter has the highest merit. FFDshow in appended to the end.

ffdshow Audio decoder however is rendering the audio portion. So I'm assuming the new Windows 7 decoder (that can do divx and h.264) is now the highest.

I tried adjusting it's merit, but I can't. Nor can I unregister the filter.

I did a search for "DTV" in the system32 folder, and it turned up :
msmpeg2vdec.dll
msmpeg2adec.dll

The two new filters? Are these in Vista? I tried to regsvr32 /u msmpeg2vdec.dll, but it failed with an error (something about access denied).

I granted my user the rights to the file, and still it doesn't help. I also copied the file out of system32, but it didn't help.

media player classic, with Haali, does use ffdshow. mplayerc with VMR9 also uses ffdshow fine.

Does anybody have any suggestions? SageTV in VMR9 mode works, but it has flickering before playing a video. It's also slow to start a video.

In EVR mode it works better, loads fast, and doesn't flicker. But still no ffdshow.

Thanks!

EDIT: debug logs, BDA errors? I think I might send this into support, but I should I considering it's Windows 7 beta?

Fixed it... I installed the newest ffdshow tryout, multi-threaded version, from here:

http://sourceforge.net/project/showf...ease_id=523000

And now with the "Default" Decoder ffdshow works in SageTV.

Not exactly sure why, I tried many things. Maybe it's just the new version.
