No yet. 

I did see the HZ=250 problem wrt DVD recording thread earlier, but I got the
impression it had to do with not being able to supply data fast enough to
the drive. 

In my case, it fails before it even write a single byte to the disc.
(Fortunately it means it doesn't ruin the disc each time I try to write.)
