Comment (by pbennett):

 After this fix, slowdown will work for all values down to 0.5x. Speedup
 will work up to around 1.3 or up to 2.0 depending on the content and your
 setup.

 The limiting factor on increasing speed is the video decoding. With 1080i
 at 30fps or 720p at 60fps the speedup can go up to around 1.3. Trying to
 go higher causes jerkiness and slowdown. With 720p at 30fps or 480p,
 speedup works fine up to 2.0x.

 If you need to speed up HD content beyond what works you can first
 transcode to 720p or less at 30fps or less.
