Hi All:Did a search but found no info on my problem.FRAPS (registered version) is working fine with the exception of the audio. I have selected "Detect best sound input" for the audio. When I start to record my flight, the audio is synchronised with the video. After about 30 seconds into the recording, the video starts to lag behind the audio, or in other words, the audio jumps ahead of the video. As an example, on a catapult launch off the deck of a carrier, when in the recording mode, all is well. When in playback mode, while viewing the panel and making my settings for altitude, climb rate, etc, the AC is stationary, but all of a sudden, the sound of the catapult firing takes place. The AC is still sitting on the deck, where it should be, as I haven't started the launch sequence. This of course is all detected by re-playing the video and seeing/hearing the unsynchronised audio to video. Not sure if it makes any difference, but I do not have an aftermarket sound card. Just the onboard audio that came with the PC. Any thoughts as to why this is happening?ThxChris

I belive that if you uncheck the box that says "NO SYNC" it will work.
