Those are the correct links. Beta (over 3 years now) it does what its supposed to do, works over 8 months for me now. Avidemux 2.6 is a ongoing work in progress and certainly not a demo program.

Most of the times: yes. It all depends on the content (odd video resolutions/audio tracks) and the used codec(s) inside the flv container. Sometimes you get a green screen at beginning, moving forward/backward helps sometime. Occasional all content stays green, using copy for both video and audio to another container might help. And yeah, it happens nothing will work, that is life I guess.
If you report back with details of problematic video and can provide a sample and If the developers have time to look at it, maybe it get solved, other times no solution is provided.

i am not getting green screen when i importing flv files in avidemux 2.6 8),

but i am getting green screen when importing iv50 codec into avidemux 2.6, for this i used avsproxy.GUI for importing into avidemux 2.6.
i saved the video, avidemux increased the output file size hugely and also iv50 codec changed into YU12 codec in output file.

pls help why avidemux increased the output video file? :'(

I believe the YU12 codec conversion is due to AviSynth?
The file increase would be due to yv12 is less compressed as IV50:
QuoteYV12 QuickTime Codec 1.0a2... is an intermediate format ...
... It's not a very good choice for end users, because it doesn't really compress video that much, and it stores pixel data in a manner that's not particularly convenient for playback. (http://www.movavi.com/codec/yv12.html)
IV50 (Indeo 5) uses video compression (http://wiki.multimedia.cx/index.php?title=IV50)

Once you have video in avidemux -> re-encode with avidemux to container you want with the wanted/supported codec(s).
Please start reading Avidemux wiki documentation (http://www.avidemux.org/admWiki/doku.php). We all glad to help out using avidemux. We can't hold your hand and find solutions/answers to every question you ask.
Good info can be found on http://www.videohelp.com/ and http://www.doom9.org/ and many other sources.
