Thanks for the reply, Dominik. ? I actually stumbled into mencoder while looking for a solution to concatenate multiple?wmv files into a single wmv file.? ? I simplified my command to remove the -lavcopts argument: mencoder -ovc copy -oac copy -o?<output file path>?<list of files to merge> ? However, I'm still not getting any audio in the merged output. ? I read about ffmpeg too.? However, I read somewhere that you have to encode the input files to mpg and concatenate them, then reencode the concatenated file to wmv.? Is this true?? ?

No. Audio codecs are irrelevant if you're using -oac copy, as long as MEncoder supports muxing that codec. > If so, how come I can play the individual .wmv files in my machine without > audio problems but I'm having the problem with the merged file. > > How can I get the timecode from the individual files to be picked up in the > merged file? > > I'd really appreciate any inputs. Well, MEncoder supports AVI and MPEG output best. Anything else works by pure luck. Thus, I suggest using FFmpeg if you don't need to use any of MEncoder's filters.
