;-), we all (and me the most) do understand this and are very gratefull 
for your fantastic work and the effort you put into this.

currently, i just assume that every VOBU contains excatly on I-Frames. 
So for fast forward, i just output every 4th VOBU. This is not the right 
way to do it.
The NAV packet that precedes every VOBU contains a table for 1st, 2nd, 
3rd .. 15th, 20th .. VOBU forward and backward containing video. The 
rigth way is now do use this field. You can easiely imaging, that this 
integrates better/gives you more possiblities with a variable speed 
forward/rewind than with the current model.

Besides that, i belive that Stefans way of describing Play/ Forward/ 
Rewind/ Stop operation mode is a cleaner way to handle the trickmodes.
