looks like you used different options for 1st and 2nd passes.

coudl you cut and upload a big enough part, along with a script containing
the commands you executed (for all passes) for reproducing the bug?

30s in .vob is around 30MB.

/dev/hdf1              77G   20G   57G  26% /home/ftp

the mphq ftp space should be enough :)
