I have a mpeg1-file in vcd-ntsc-format and an audio stream in a different language in mp3-format. But as the mp3-file has a variable bitrate, TMPEGEnc can't join them together. When I tried to convert it to 224kbps and create a vcd-file, the sound was really bad.
VirtualDub can't handle the video- or audio-files.

What program can I use, to join these files? I don't need a vcd, just a file I can watch on pc!
