NewVideoRecorder is a high quality video capture toolkit for Linux. It includes deep buffering of audio and video to reduce frame dropping, a smooth dropping algorithm to keep the video smooth if dropping is required, and dynamic stretching of the audio stream to exactly match the video stream. It can use v4l1 and v4l2 devices as video sources, and OSS devices as an audio source. It can produce QuickTime, AVI, NuppelVideo 0.52 files, MPEG-1 files, and all files supported by ffmpeg (through the ffmpeg library). It also includes tools and utilities for high quality video streaming (multicast and unicast).

Could you please contact me by email (justin at suntiger.ee.up.ac.za), and attach the file config.log? There should be some clues there as to what went wrong...

There are two key enhancements:
1) Dynamic audio warping. The audio stream is warped (during recording) to exactly match the video stream. Most other recorders loose synch after a couple of minutes (or hours, if your sound card is good). I have a stream here that has been running for nearly 2 weeks, and the A/V packets are still perfectly synchronised.
2) Deep buffering. Both the audio and the video are deeply buffered (with hardware support where available). This means that you are much less likely to loose frames under bursty load.
3) (Actually part of 2...) Smooth frame dropping. If it should happen that frames must be dropped (i.e. your system is just too slow to handle the capture/codec), then the frames are dropped in a smooth, regular way, to minimise visual degradation. (In fact, its hard to notice until you start dropping nearly 20% of the frames!)
Some of the competing projects have some of these features, but none have all of them (in fact I know of no other recorder that dynamically warps the sound, although some do provide a post processor to fix the sound afterwards).
