I've once asked about this from Klaus and he did not see this feasible at that time. If I remember correctly he thought that this would be something that should be done in the device itself.
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.
So I am not sure in which direction this feature request should be aimed at :)
Originally I had this idea from my JVC hd recorder which has 1.5x playback possibility. Sometimes there are programs that you just wand to speed up a little :D
Oh, and ofcourse subtitling should work also as it does with PowerDVD.

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?

Me too, although I would be happy even if the pitch changed.
But is this something that can be done entirely on the VDR side? I would tend to believe that the decoder needs to be modified as well. In other words, it could be made to work on softdevice and the like, but not on (m)any full-featured tuner cards.

You may have a point there. Maybe this could be done using mplayer plugin? Mplayer can change the speed but the pitch changes.

Users of vdr-xine my want to try xine's stretch audio plugin. Just add
--post stretch:factor=0.6667
to xine's command line for 1.5x speed. But maybe it's a better idea to add it via xine's audio post processing dialog just when watching a recording, as it doesn't work well when watching live TV. The satellite won't speed up to broadcast at 1.5x ;-)
Bye.
