Well I was just watching a DVD with PowerDVD windows player and it has the ability to play back with 1.5x and 2.0x speeds with sound. Without changing the pitch. And that has to be done with software since I have no kind of hardware to do that. I know that mplayer can play with many speeds with sound but the pitch changes also.
I think this would be very nice thing to be done.
Mythtv supports this and it was really nice to 'speedwatch' a program while it had already recorded some minutes and when one caught the realtime transmission, it switched to normal speed.
Configurable time-skips with different buttons would be nice thing too :)
Is this really the case that only the two of us are interested in this cind of functionality?
