I apologize up front, because I can't help you with your question, but thought I would add my observation:

The first one you listed you said worked, and its only $35. I bet you spent $35 in time trying all that software.

Often you get what you pay for...free sometimes doesn't deliver everything you need. Now if the first one was $300, I can see trying other solutions...

I haven't found anything that works with all FLVs because many files are created with audio/video sync error.

I typically use:

FLV Extract to separate audio and video into 2 separate files, an MP3 and an AVI.
Convert the resulting MP3 variable-bit-rate (VBR) file into something with a constant-bit-rate (CBR) like a WAV file.
Bring the two files into a full video editor and sync by hand.

I've only done this with a few FLVs because most aren't worth the effort.

Note that ffdshow is required to be installed for the resulting AVI files. That could be your problem with "SUPER". I am using "ffdshow_beta3_rev1324_20070701_clsid.exe" within Windows XP.

If you simply want to merge the 2 streams (audio/video) into a playable AVI then something like VirtualDubMod works fine. Sync may be off but that's because they are off in the original FLV. Trimming or padding the audio file may help provide a more acceptable sync without full re-timing.

i go to try SUPER with ffdshow_beta3_rev1324_20070701_clsid.exe
meanwhile thanks to all
bye

I think total video converter is the best for audio and video syncing problem.
Sometimes the converted flv has been out of sync which can only repaire with video editor software.
