You might want to take a look at ffv1rec that comes with avidemux
(http://avidemux.sf.net). Its based on nuvrec from the nuppel tools and
allows capture in an number off ffmpeg codecs, but uses a nuv wrapper
rather than avi. These files can then be edited down using avidemux and
saved as DVD/SVCD/MP4 etc
