I used avi2dvd to convert a mkv file. It plays back on my stand alone dvd player except the audio is delayed a character in the film will speak and the audio will be delayed a second or so behind. I would be very grateful if anyone can help. Ow im pretty sure the mkv file plays fine on the computer but I will have to check this to be certain. Thanks.

I never dealt with MKV (Matrioska) files, but it seem you need some kind of 'demultiplexer' which extracts the audio content from that movie; later yu'll need to 'decompress' the audio stream, which probably was compressed MP3 VBR instead of MP3 CBR.

Get MKVToolnix
http://www.bunkus.org/videotools/mkvtoolnix/win32/mkvtoolnix-unic... ,
MKVExctractGUI
http://corecodec.org/projects/mkvextractgui/
and, finally, FFMPEG GUI.
(Videohelp has a nice page on it http://www.videohelp.com/tools.php?tool=434)

If needed, install Lame.

========================================================================
Extract the MKV* files in the same folder (MKVExctractGUI needs the MKVToolnix files).

Extract the audio stream from the MKV with MKVExctractGUI.
More likely, it was MP3 VBR and you need to decompress it to WAV, before converting it to a DVD compliant stream

Later, convert that WAV into an AC3 192 kbps 48000 Hz with FFMPEG GUI and author the DVD adding the video only + the new AC3 audio you just made.
