But we all live in a world of multisession and non-multisession.
My old record collection, I could not even make a record. I could not mulisession anything. My original music CD collection I could not mutisession. I could if I transfered it to Cassette tape however.
Its only been in the later years that even Data CD's coule be made multisession and readable on most cdroms. My 2 year old Toshiba DVD rom will not see past the first session of a DVD Mulisession data disk, but can for a CD.
Maybe the use of DVDRW's can be a compromise.
All I can suggest is you try and contact the Motion Picture Expert Group (MPEG) who set up all the MPEG1 and MPEG2 standards we use today and voice your dissaproval of not being able to multisession a DVD. Best of luck.
