half-speed play with no audio pitch change? (almost clueless)

[gregconquest]

I have a particular video, "OH! Mikey" (wikipedia info) (http://en.wikipedia.org/wiki/The_Fuccons) (piratebay info) (http://thepiratebay.org/search/Oh%20Mikey/0/99/0), that has very fast spoken Japanese with English subtitles. I want to play it at half-speed -- the video and the audio both slowed down, with no pitch change, so I can read the subtitles and understand what is being said. I remember WinDVD or PowerDVD had this feature years ago, but I cannot find out much about it on any player now. Either this control is a specialized feature that is not widely supported, or I'm using the wrong search terms, "slow motion", "pitch change", . . .

I originally asked this question here at videohelp.com (http://forum.videohelp.com/topic350432.html?sid=fa86cfc617dc526b47884dc797ce0775#1845630), but they advised me to try doom9 and perhaps avisynth . . .

I am mostly using linux (ubuntu), but I do have a Windows XP PC available as well. I don't have Vegas Video, Premiere, or any other big commercial video editing apps installed now.

So, can anyone here give me suggestions as to how to play this video at other speeds? And since it is mostly this one video I want to play slow, is there a way to transcode it to always play slower in any player -- to basically double the file size rendering every video frame twice while doing something analogous to the audio?

Thanks for any help,
Greg Conquest
