A 5-year-old post, but if I found it by a search others might too ...
I'm still using an old 800 x 480 phone (Toshiba TG01, but I expect other phones of the same resolution will behave the same). Handbrake has a Windows CLI version. I sometimes want to convert .ts or .mp4 files to play on the phone; I use Handbrake with standard configuration and presets, and the following works fine for me. I tried playing with Handbrake parameters, but usually got either jerky video or digital pixellation. The following may not produce the very best possible output, but it's unjerky, uncorrupted, and displays and sounds fine on the phone display and headphones; it's not worth fiddling for ages.
I have the following command stored in a text file:
"c:\Program Files\HandBrake\HandBrakeCLI.exe" --preset "Apple 240p30" -i "input pathname" -o "output pathname"
The input pathname is the path and name of the file to convert, which must have appropriate extension (e.g., .ts). The output pathname must end in ".mp4". I simply edit the pathnames and paste into a Windows command window. I suppose some Apple-specific things are done, but the output is fine, and small. A 1.6GB .ts file (film) recorded from standard-resolution television reduces to 300MB. Maybe "Windows Phone 8" (available in Handbrake 1.0.3) would give noticeably better resolution; there are plenty of ready-made presets to play with.
(I generally prefer CLI to GUI programs for this sort of thing; once I've got the options right with the GUI or CLI version, I just make a batch file with appropriate parameters, or copy and paste to a command prompt window.)
HTH
