It is my opinion that HandBrake with an importable preset for N900 friendly converting is easier for windows users than using most anything else. Especially for users that know nothing about A/V encoding.

I don't want to downplay Jaffa's tablet-encoder... On linux, it integrates right in with what Linux already is and does and has - 1,2,3 you're done... but on Windows.. I don't really think the installation of mplayer, perl, mencoder, and possibly cygwin are within the realms of what "normal" users want to be doing.

If we can get windows users to the point that they simply "Install application A, Import Preset B, Profit".. it'll be the easiest solution.

If somehow Jaffa gets a windows installer/wrapper that includes (automatically) both perl and mencoder or cygwin.. that would be awesome.

This is all just my opinion.. don't mean to offend anyone.

ETA:

It is also my opinion we should have a wiki article with all of these options details in a step-by-step. Including the installation of tablet-encoder on Windows, Linux and Mac, as well as 3 presets for Handbrake (normal, good, best) video qualities. Would need to maintain two presets in some cases it seems, since windows lacks some options that Linux/Mac have. Maybe DVDFab as well.
