bttvgrab is a program for grabbing video sequences using a bt848-based frame grabber card (e.g. Hauppauge WinTV, Miro PCTV...). The goal of bttvgrab is to provide high-quality grabbing suitable for video recording. Currently, this is accomplished by trying hard not to leave out a single frame, and to catch temproary delays by buffering several frames. In the future, synchronized sound will be part of it. Then you can create mpeg movies using mpeg2enc, the output files will be prepared for that, so that the conversion can be done by a simple shell script.
Bbb is a set of utilities for burning to CD-R and CD-RW media.
