DV encoder for linux or windows?

As i know so far, non-free tmpgenc on windows performs much better than ffmpeg and mpeg2enc on linux, especially with low bitrate. Achurch gives a rough comparison among them.
Anyway, if u stick on linux to encode DV, seems mpeg2enc has not too bad quality and ttmpeg is definitely much faster.
As i am a beginner (actually, have been a beginner for years, maybe forever. :-) ), i donnot care more, To edit video on linux, here is a more complete reference, and a very long discussion is here. there is a list of great softwares on linux for movie production.
