    Hi, I have some mkv movies that I tried encoding. The MKV's play perfectly in media players, but after I encode them to DIVX .avi, with .wav or constant-bitrate .mp3 (converted from .ogg), the audio is always off, and gets worse by the end of the video. I already know how to demux and convert .MKV's to AVI (I did several series with no problems), but I never had this problem. I've tried using VirtualDubMod, Nandub and SubMux (VobSub). The framerate of the extracted avi, I checked with Gspot is 29.971, but when I rightclick the MKV file's Properties in windows explorer, it says 29.96999. Both audio and video are same length of time. I don't know why the original MKVs play ok, but the encoded .avi videos have audio sync problems. I've tried skewing audio, messing with interleaving, but nothing works. Can anyone help?

    Probably the mkv is VFR (Variable Frame Rate). avi doesn't support VFR so the video becomes CFR and the audio no longer matches.
