Reformatting help

can anyone please tell me if this is normal a have some shows on my memorex dvd+rw 4x 4.7gb 120 min video disc. i remove it for a hour or so then put it back in to use it i have to reformat it again why? i have a panasonic dmr-es25

thank you

The ES15 has major problems with DVD+RW media, when a DVD+RW disc is inserted it will try to reformate it. You can record to DVD+RWs then play them on another player if you make a menu. To avoid the problem use DVD-RW or DVD-RAM if you must, I use DVD-Rs as I hardly ever reuse a disc after recording.
