Avidemux 2.5 is dealing with frame number and does not care about timecodes, which might produce AV sync issues. You don't lose quality by opening a file in one or the other way, but you will lose quality by re-encoding the file.

Did you name the videofile "avidemux" and was vlc showing the filename near the bottom of the screen?

It is unclear to me what the first issue is, after reading your post.  Can I ask you to explain some things for me, please?  It will help us to help you.

Ok are you on Mac OSX Lion?  Are you using the really new VLC-2.0.0 from http://videolan.org ?

What program did you use to convert your video?  Did your video start off as an avi or a flv or wmv, or what type was it?

We will figure that part out for you after you reply.  Good luck.  I hope we can help.

After an encoding avidemux writes its name in the "Name Field Tag" of your video, even if you save it with correct name.
If you want check it, use mediainfo which can read tags of video file.

I updated vlc last week.i converted an flv from youtube to mkv.i need to:
Crop black boards
Vertical flip
Rotate by 180
Mplayer resize (lanczos)
I'll need to re encode it,because it doesn't allow me to do the things abovein 'copy' mode
