I've had my E50 for a couple of months and while I'm happy with its performance on RAM, dvd-rs made on it seem particularly badly written compared to those made on my Panasonic PC burner. I have a Tosh 210 dvd-player, which seems pretty fussy about playing dvd-r from any source (though others seem to have no problems with dvd-r on this machine). However, I've noticed that even my Pioneer dvd-115 pc reader struggles to read dvd-r media written on the E50: either not recognising it at all, or having unreadable sectors near the end of the discs. Both my PC burner and E50 can read any of these dvd-rs fine, but the fact that the Pioneer can handle dvd-rs written on the PC (at any speed) with the same media, but not those written by the E50 indicates that there's an issue with the write quality from the E50. I've tried Go-gos, Ritek G03s, G04s and Panasonic branded dvd-r media, but the results have been similar whatever I've used. Could it be that my E50 has a weak laser assembly or is this a characteric of E50's in general? Even though I've tried Panasonic media, is there any other brand which guarantees a good burn on this machine?
