whats the best linux software for capturing MPEG 2 DVD format?

I have a DVD+RW -RW drive that what to be able to capture using my capture card with vcr using composite video , with the stereo line in connection , it works just fine in windows using either MYDVD software & or nero 6 software but nero 6 seems to have problems capturing with my capture card , also cyberlink PowerDirector 3 works in windows xp pro for this too

my drive can burn either 4.7gb or the double density 8.5gb dvds but , I have found linux versions like redhat, gentoo , suse 8.1 to lack direct capturing able to capture to mpeg , its fine that they can capture avi but avi is not as good as mpeg for videos etc..

does anyone know of the best free DVD capturing and authoring software for linux? I know about k3b I think If I remember right that it can authorize dvd but how about capturing directly to DVD mpeg2 format for linux?

I don't what to convert form avi to mpeg or anything like that, if so I would stick with windows for mpeg2 capturing for know , unless someone could tell be of software in which I am looking for,

Linux does have pluses thou like net access for http pages seem to access faster then windows using lucent (winmodem) , net access is a little more faster in linux with msn connection why is that, also I like that you don't have to worry about virus what much in linux compared to windows based software.

but the down side to linux again anf again is its lack or well just lack of being windows / dos games compatable , like for example I don't think I will be able to play say my doom 3 under linux any time soon , I know that UT2004 works in linux but , their are so many games that don't and maybe will never run under linux , like for example cyan games like myst and URu ages after myst or realmyst , or any games that not 3d or shooters based games, or the Simpsons hit & Run game i don't think it works under linux , wine is ok, but its far from usable with all games, I mean when do you think linux is going to be 100% Directx 9c compatable with SP2, any games that come out based on directx technogle will must likely not run under linux unless linux is allowed to keep up with Microsoft Directx Fixsor patches as it were , also SP3 for XP come make it so all directx based games what come out for it could in theory make or break compatable with linux , and the same thing happen with harddrives when microsoft makes that next windows , format in their harddrives they could make it so linux could never install on them with longhorn windows systems, whats to stop them from breaking their systems to be able to use linux in the future computers?
