.m2p convert to s/vcd??

[2xdown]

I got a file of a concert that someone had taped off of a website that a friend of mine runs, but i cannot figure out how to convert it to a usable mpeg/2 so i can burn a s/vcd... when i load it in tmpgenc, it tells me that the audio track cannot be recognized, and then when i attempt to capture the audio with virtual dub, i get another error message... at this point i have no clue what to do... any suggestions would be helpful...

try changing the file extension to .mpg and that should work.
