no, but i belive it could be done in vdr. The first thing we need is to get 
the conversion to DVD compliant PES stream. mplex is doing this, so we could 
borrow this code. In this stream the PCI/DSI packets need to inline. They 
contain forward references, so they need to be fixed after the recording is 
complete. PCI/DSI packets are also the cell/VOBU boundarys. As soon as the 
correct position of all PCI/DSI packets is known, the ifo's can be generated.

The biggest problem is that the PCI/DSI packets contain absolut block 
adresses, those obviosly depend on the excact position of the VOB on the dvd.

yep, i think mkfs.udf exists.

No existing tool, we would have to build then out selfs, me thinks.....
