is there a 4 times or 8x play mode?
perhaps a mode that drops picture quality of playback while increasing the speed of playback?
This is useful if, for example, you have 5 hours of video and you're looking for a minute here and a minute there,
What I've tried,
1. set rate (Ctl-R) to 150, and set the option 'drop frames when behind'
the problem here is that playback gets very jerky and occasionally this will drop 100 frames and you could miss what you're looking for
2. Alt-left-button, skipping ahead by 50 frames each time. this is OK as far as it goes,
3. with both 1. and 2. above, setting the priority to high or realtime.

It would be very easy to do this by using Avisynth (www.avisynth.org) scripts, where you could just use for example use SelectEvery(100,0). That would output a video where only every 100-th video frame would be shown.
Dropping picture quality for faster playback is not something a video editing tool can do, because the quality and speed of playback is mostly determined by video compression codec, and can't be in most cases adjusted.
Also video clips mostly have a framerate of 24 - 30 frames per second, so that accelerating that 8 times would end up in at least 192fps video which is much more than the monitor refresh rate (mostly not over 100 Hz).
