This depends almost entirely on your PC specs. Users with high-end i7 CPUs are reporting conversion speeds of 300-500fps. Hopefully the new DVD to Mobile engine will be faster for you, it should be out before too long. To improve speed with what you have, try converting from a VIDEO_TS folder on your hard drive rather than the original disc and use an audiocopy profile if your player supports it (AC-3 for most DVDs). VOB Passthrough also is much faster than an MPEG-4 conversion, but again your player must supportVOB/MPG playback and the files will be larger.
