The same problem with flv videos downloaded from SVT. Avidemux 2.5.2 (1:2.5.2-0ubuntu3)
After remux with mencoder, avidemux can read the file for editing or transcoding. Tested with two videos from SVT and with pjw's 10 sec sample.
mencoder -mc 0 -oac copy -ovc copy -of lavf infile.flv -o outfile.flv
(The flv files from SVT have B-frames so avidemux must use safe mode which affects seek precision. The 10 sec sample does not have B-frames and don't need safe mode. A/V is out of sync in avidemux, but not in totem and mplayer.)
