I'm experiencing something strange. Some Cineform clips do not have audio when played on Media Player Classic or Windows Media Player, but have audio inside the NLE. I already tried to check the settings on the players but couldn't solve the problem. Any idea?

There are other Cineform clips that play audio just fine in the players. But some wont. Only inside the NLE.

Thanks.

There will be a reason for this (missing audio codec, or similar.) It is a question for support, and they will need short sample clips that do it. File a ticket at CineForm Support (http://support.cineform.com)
