My father in-law has the Philips DVDR70 recorder, I am having trouble playing back disks he has recorded onto DVD+RW disks. From what he says these are not finalised on the Philips, is this true? If so I guess thats the cause of the problem. Is there anyway to finalise DVD+RW disks on the Philips machines? I am trying to play them back on my Toshiba RD-XS32. The disks work fine on my Panasonic DVD-LS50 portable DVD player, and my older Sony DVD player so obviously I appreciate it could be incompatability on the Tosh which is the problem.
