speeding up a network stream is unwatchable

[knightknight]

Hi, I'm trying to watch a lecture stream -- mms:// -- with 2x speed. After a few seconds of watching, though, the stream stops. Then it either keeps counting the time or it eventually starts up a few seconds ahead of where it stopped. This happens continuously, and the stream is unwatchable. I set the http-caching to increasingly higher numbers but this kept happening, just at longer intervals. E.g. 1000ms -> I had to wait a few seconds before it started playing, then it gave me a few seconds of no-hesitation playback but then the problem again. 10,000ms -> I had to wait 13s before it started playing, then it gave me 20s of no-hesitation playback but then the problem again. 60,000ms -> I had to wait 60s before it started playing, then it gave me 2min of no-hesitation playback but then the problem again. So according to these experiences I would have to crank the http cache up to 900,000ms then wait 900s (15min) in order to watch the 1-hour lecture at 2x speed with no stuttering, which is just unacceptable and unwatchable.
Any way to fix this? Thanks!

Note: this is the same on a PC and on any number of Macs my friends have tried this on. I have no problem in Windows Media Player, but I'm trying to get this to work on a Mac so WMP's no help.

Not sure VLC implements speed for MMS.

Anyone else have an idea? Can this be fixed in the next version? Or if no ideas, anyone know of other Mac players that would allow me to speed up a network-streamed mms? (Tried some Mplayer variants, didn't work well.) Thanks all.
