Back when I had my e50 (a whole two weeks before returning it in frustration), I bought a bunch of Panasonic brand dvd-r's to try because I was having problems with it liking the Apple discs I usually used with my a03 (though they've never made a coaster on the a03). I figured if anything would work well in the e50 it should be Panasonic's own discs. They did indeed work pretty good, and I think out of the 10 I bought only one had any problems (and I think that might have been due to the possibly defective e50 recorder, not the discs). Only down side is that they are some of the most expensive dvd-r's out there.
