anyone with extensive ffdshow (directshow/vfw) knowledge?

Having an issue editing with Adobe Premiere, can't get ffdshow to win the "I'll do it" war over whatever piece of shit codec Windows is using to try and decode my MJPEG AVIs, so it skips frames and only plays the audio in Premiere's preview/timeline...I've been trying to figure this out for three days with no luck(google and the like), anyone well-versed in ffdshow/vfw codecs that can help me solve this puzzle?

In what capacity do you have ffdshow installed? Via a codec pack or stand-alone? Also, what OS are you using? Assuming mjpeg is set to libavcodec in ffdshow VFW, I guess the main problem would be for windows or Premiere to recognize the preference. The only two things I can think of are dependent on a few things and I'm not even sure if MJPEG is a format that's supported unless it falls under another category. The first being using CCCP to set the ffdshow preferences and the second being using win7 dsfilter tweaker to set the preferences, with the first obviously needing CCCP and the second needing Windows 7.

I have ffdshow installed standalone, and mjpeg set to libavcodec in ffdshow VFW config. Google revealed that MJPEG is supported by PP CS4 because someone had the same problem I'm having, but the solution that worked for them was reinstalling ffdshow because ff_vfw.dll was missing. It is on my Win7 laptop if you want to elaborate on that dsfilter tweaker(though I thought directshow was for viewing and vfw was for editing?), what I'm guessing is happening is that a VFW codec in windows is decoding it and taking priority over ffdshow, since ffdshow doesn't even show up in the tray/task manager when I have the clip loaded in Premiere.

Win7 dsfilter tweaker is meant to set registry preferences on whether to use microsoft or installed third-party codecs for decoding various formats, so it could work, but since there's no explicit MJPEG category, I don't know if it'd do you any good. Here's the link if you want to check it out, though: http://www.codecguide.com/windows7_p...er_tweaker.htm

Sorry if none of this helps, I've never used Premiere before and have never had to configure VFW, but I wanted to throw a few things out there in case getting the thread going might encourage others to share any input.
