I'm not that familiar with DVD burning, but here is what I tried to make myself a dvd using a Verbatim dvd-rw disc with both the pioneer and lg writers I get an error: Track 01: 0 MB written.dvdrecord: Input/output error. write_g1: scsi sendcmd: no error I get a similar error with cdrecord-prodvd too. Any help would be appreciated, I have shortened the output for brevity. -Mike mkisofs -r test.tar.gz | dvdrecord -dao -v fs=6m speed=2 dev=0,0 - dvdrtools v0.1.4 dvdrecord: Warning: using inofficial version of libscg (bero-0.5a '@(#)scsitrans p.c 1.81 01/04/20 Copyright 1988,1995,2000 J.
