I've just added subtitles to a wmv file (HD 16:9) - great, the video quality is perfect, but I want to keep the original audio, so how come it won't sync, even if it's the direct copy from the original source? I've even saved the audio to a wma with Sound Forge and imported that; same problem. Could the subtitle encoding (with TextSub2.23 + an .ass file) somehow mess up the framerate/framecount so it's the video that's oos? Quirks with the wmv plugin?
I'm at my wits' end. Should have delivered yesterday already.

Just tried a very short sample encode after importing with avisynth, and it looks alright. I'll only be sure after I check the full monty, but this was the avs code:

CODE
DirectShowSource("video.wmv", fps=25, ConvertFPS=True)
EnsureVBRMP3Sync()


halfway down, under "My sound is out of sync", here:
