Using mp4 because flv doesnt support multiple audio tracksDoes the problem persist when you use vlc to play back your recordings?
lol didnt read the question right :PThat does not answer my question in the slightest, and you should use mkv for multitrack recording anyway.
Thanks it workedDon't rely on windows media player to actually have good media format support. You're just setting yourself up for a LOT of disappointment.
Use VLC instead.
