DVD DEcoders can FF w.out changing pitch. Why not ENcoders? PERFECT for mobile video.

I own a Samsung YH-999 Portable Media Center video playback device. Some DVD decoders (Like NVDVD) can FF (Fast-Forward/speed up the movie without changing the pitch of the audio. This can shave a lot of time off of a full-length movie. I need to find a way to do this with a ripper/encoder! Is this possible?

Because I can only enjoy my content on 15-min breaks at work, I'd like to re-encode all sorts of TV shows and movies at higher speeds so I can finish them faster. eg, watch a movie over several breaks or watch a 30-min TV episode in a 15min break (Manually skipping intro, credits and commercials of course). Of course, I'm not going to do any editing or removing commercials before encoding because I will simply be watching once AFTER encoding and later deleting them. If I did any editing, I would have basically seen it and deleted it already. ;) Basically, I want to set up a system where all my recorded content for the day gets processed like this over-night and is ready for viewing at work the next day.

A little help? If it's not possible, who should the feature be suggested to or requested from?

Watching movies on the fast lane, huh?

You can use the audio software of your choice (i.e. goldwave) to speedup/slowdown audio without changing pitch. if FFTs are used it's very high quality.
For the video the simplest is to just change the fps. If you want to speedup 25fps material by 60% set it to fps=25*1.6=40.

But make sure your mobile device is fast enough to handle that. If not you have to drop frames.

Well, because the device only supports 320x240 800kbps (max) WMV9 I was tooling around with WMEncoder9 and found this:

Works like a charm for an episode of Reno 911 (DVD rip)! Now all I have to do is figure out how to overlay Closed Captioning so I could set it to a ridiculous speed and still interpret the results. Yeah, because Reno 911 is a TV show the DVD has no subtitles and uses only CC.

I'll still probably need to do it "your way" when I get to tooling around with DVR-MS. I could set up the Media Center to record the news and if I can process the resulting DVR-MS file correctly with overlaid captions I could just fly through it in half the time.
