I've just bought a Panasonic E85 and am looking to buy my first batch of blank DVD-Rs. These will mainly be used for long-term archiving. After reading posts on this and other forums, the Verbatim and Panasonic blank media appear to be very reliable for use in Panasonic machines. However, I've also read comments about the Verbatim discs saying that it's better to buy the ones that come in cases rather than the ones on a 25 or 50 disc spindle as the spindle discs aren't as reliable. Are the blank DVD-Rs that come on a spindle any different or inferior to ones from the same manufactuer that come housed in individual cases? I'm tempted by the offer on the Panasonic E-Shop for 50 DVD-Rs on a spindle and 20 DVD-Rs in cases for £60, but would appreciate anyone's comments and experiences on using discs on a spindle.
