Over the years I have purchased thousands of blank CD's and DVD's and the best ones i have come across are in fact, RiDisc ones. These discs are not quite as good for audio playback but are very reliable and I personally have never experienced issues related to buffering, corrupting or loosing data.
So the first thing to note is that these are not as good as the RiDisc AAA+ DVD±R's (which cost just pennies more) and i find give better audio playback in a DVD player. I burn DVD's with music files on which can be played in a DVD player at 128KBps, and have noticed that these do not give the same depth of the sound, particularly bass frequencies. The MP3's sound great on the computer in high quality audio, and still sound great in the DVD player on the RiDisc ones, but they sound like they have lost their quality just by being burned on these discs?
All files types on the disc are burned quite nicely though, without causing them to corrupt or "go funny" as it were. The video playback is relatively good compared to some of the much cheaper brands i buy and where picture quality is concerned these are great but where audio quality is concerned, again it sounds like the quality has dropped simply by being burned to these discs.
Burning is great with these, at full speed of 16x they burn quickly and without fault. I have had 1 duff disc out of 100 so far and that's good going given that all discs no matter what quality, have buffering issues at some point. The burning is done effectively and whilst over burn will ruin the disc, they do fill up to the brim quite nicely.
Usually with just a couple MB's to go, some discs will over burn despite claiming to have 4700mb, yet you burn 4699mb, and that's because not all cheaper discs are exactly equal. These are quite good value for money at around £10 per tub of 50 and all discs are equal and will fill up to that over burn limit without claiming to be full. Sometime's as i know to well, that 1MB is very important, unless you want to burn another disc.
These are good quality and good value for money discs and i would recommend them but if you are happy to spend more money and want better discs for your precious stuff like family photo's, buy the RiDisc DVD±R ones which are pretty much the Rolls Royce of blank DVD's.
