Not sure beyond "25 Mbps max." I don't have the Blu-ray spec handy.

2. So definitly L 4.0 dosen't require slices? can be then L 4.0 video primary video?
Yep. You could even use AVCHD spec for primary video.

3. What is max allowed vbv-buffersize and vbv-maxrate for Level 3.2 from blu-ray specification for SD content, and what resoultion and fps allowed for SD, and is L 3.2 maximum for SD?
Sorry, no idea.

4. Is there anything about BD5/9 and special restrictions such as VBV or other?
It's been recommended to use lower peaks for red-laser media for better accuracy. 3x has been bandied about (like the HD DVD "3x" mode), for which 25 Mbps video would be a fine constraint.

That said, BD-on-red-laser isn't something that a lot has been done with, and I expect we'll find significant theory/practice divergence, particularly on early hardware BD players.
