Sounds unbelievable strange! It is possible to switch from 2048 -> 2358 but
not to reverse this?
Is this related to SCSI drives only, or is this a general issue? My
workstation has both: An IDE DVD-R burner (so it has a IDE-SCSI emulation, and
a SCSI CD-Writer (a true SCSI device).
If only true SCSI devices are affected, does possibly a SCSI driver reload
help?

Oh! -- So what have you changed? Is it required to recompile the whole Linux?
Shouldn't it be possible to re-set the Blocksize to 2048 with a little C
program? It would also be an idea to fix this in mplayer/mencoder, so that
they switch everything back before exiting?
