...read-write disk to use in coping pando movies? i have tried to use a reg. read-write disk, but i don't know if it is the right one..i've tried right clicking on my pando pacakes on my c drive to send them to my 'd' drive where my blank disk is in hopes of coping my movies as back up to free my space on my "c' drive, but this has not worked well...and i have 'sonic coping software on my dell, computer, so what i'm i doing wrong with this process or do i need to try a different approach or contact Pando for help?
