DirectShowSource: The file is not supported.

Hi guys, hope you can help me...I'm going nuts here.
I've been converting many 720p MKVs (H264 high profile@5.1) to MP4s with the help of StaxRip.
It worked always great. I added the file, Staxrip demuxed it and then I could edit all the settings and voilá it was done.
But I got this ONE DAMN FILE. It's a h264 mkv, just like the other ones but it always gives me the following error after Staxrip demuxed the file:

I've tested different versions of Avisynth but other files are working too :(

The avisynth script that is being created:
DirectShowSource("Z:\movies\hddvd_bluray\AB.264", audio=false, convertfps=true)
Crop(0,0,-0,-0)


logfile:
------------------------------------------------------------
Source script error
------------------------------------------------------------

DirectShowSource: couldn't open file Z:\movies\hddvd_bluray\AB.264:
Cannot play back the file. The format is not supported.
(Z:\movies\hddvd_bluray\AB_new_Source.avs, line 1)


Thank you very much!

Raw files are not supported by DirectShowSource. Use DGAVCdec instead.

Thanks that worked :) I've just added the .h264 file to DGAVCIndex and saved the file as .dga. Staxrip then could continue it's work with that file. What I can't figure out is why Staxrip didn't do this automatically. I mean that's what it has done with all the other files...
