I originally posted this in the General Discussions forum, and no one has been able to help. It seems like a bug, so I'm submitting it here:
I can't get any of the flash videos I download from the web to simply copy into the same flash format--if I could get this working, I would eventually like to be able to set the "time" start/end points so I can clip the videos. I always get the "no file outputed" error. [BTW it should be spelled "outputted" in case you want to correct it, Stanley]
Under "Audio", I select "auto select" for source, then check "enable audio" and "copy audio" so that no transcoding is necessary. Under "video" I check "enable video", "copy video" and also check "auto select" for "source" and "backend".
In case it helps, below is the complete output log from the console window. Also, I'm on Windows XP SP2.

=============================
Can't do simple flash video --> flash video conversion
The new build seems to make the difference--I was at least able to duplicate the flv using your settings, Mixer, which were actually the settings I used originally.
BUT, setting the start/stop times does not work. For instance, for a flash video that was 60 secs long, setting the start time to say 31 secs and stop time to 60 secs does not give the desired result; The final video is still 60 secs long, but the video/audio are "frozen" until it reaches 31 secs, at which point the video/audio continues as it should. Setting the end point to say 45 secs has absolutely no effect on the final outputted video--the video still plays as normal until the end at 60 secs.
Any ideas?

Yes, tried using "select" and then using the "clipping and effects" dialog window; actually it worked even less correctly than filling in the start/end manually, because when I clicked on OK to accept the start and end points, it only filled in the start position and left the end as 00. This is of course didn't work.
