Totally idle speculation, but could you use the 'pipe through vlc'  
option to recode the video to the speed you want, effectively dropping  
frames?  That would preserve, or even reduce the data sent to the mvpmc.

If vlc can re-encode a video so that it plays backwards (can it?),  
this could also produce 'flowing' rewind.

Unfortunately, I think this would be made pretty unusable by the set- 
up time (ie stop playing current video, send command to vlc telnet  
interface, start playing newly converted video received from vlc).   
Wouldn't be worth it for regular x2 ff, but for 'skimming' a video it  
could be pretty useful.

The start up time might be reduced if the video was already being re- 
encoded by vlc, ie mvpmc doesn't see that as a new file---you'd just  
be changing the vlc command ...

Or perhaps the Mythtv backend can do this type of on-the-fly re- 
encoding? As I say, idle thoughts :)
