Can't open FLV with Avisynth

[Greensmurfet]

Ok, I have read just about every guide or help thread I can find either on here or other forums and I still can't open FLV in vdub.

I'm able to open the FLV with MPC. It says its an Mpeg4 h264 and audio is AAC 44100Hz. Frame rate is 30.0 and for codec id:7.

I have tried for my avisynth:

directshowsource("C\....")
directshowsource(C:\....",fps=29.97, convertfps=true)

I was getting a different error before. This is what I'm getting now. "Could not open as video or audio." Both are returned and it says "The specified module could not be found."

I have downloaded:

ffdshow rev 3984_20110922_clsid
ffdshow tryouts beta7
directx june2010
dgdecoder.dll for avisynth
flv input driver
dshow input driver
gabest video splitter 1.0.0.4

Possibly downloaded other things to try to get this to work. I can't get WMP to play the file. I believe I registered all dlls and ax. I went into ffdshow VFW config and video decoder config and made sure to set h264 and flv1 to libavcodec. At this point I'm ready to uninstall everything and start over but I would like to know if I'm just making a dumb mistake. Am I missing something?? This is driving me crazy!

Oh and I have vdub 1.5.10

Thanks in advance
