Summary: Not as good as Ritek used to be
Review: I got 2 packs of these few weeks ago. So far I got 1 coaster for my first pack and 3 coasters for my second pack. I have used NEC 2500A burner 1.07 firmware to burn these DVDs at 4X using DVD shrink and Negro. In the past, I have burned successfully 50 pack Ridata 4x DVD-R without any coaster.

Summary: Great affordable media
Review: I just received my 25 pack of these Ridata 4x dvd-r's and I'm VERY impressed so far... in fact I just ordered another 50.(I recently tried some of those "grade A" dvd-r's that lots of people are selling on the internet, and while they do burn at their rated speed of 4x, 99.99% of the burned dvd's won't play back on any dvd player I own, including the drive they were burned with.) With this in mind, I decided to try the Ridata brand of Ritek dvd's.
I have used other quality media like Imation & Verbatim with excellent results, and those discs had a mfg id of Ritek G03... exactly what these Ridata discs are. Imation & Verbatim 2x dvd-r's usually cost over a buck each. My dvd-r/+r/-rw/+rw burner has been a bit sensitive to the media it will burn and so far every one of these Ridata discs have burned perfectly & at a max speed of 4.0x.
So far every one of the discs I've burned have played perfectly in all of my dvd players & drives too. BTW: A normal 2x dvd-r burns 4gb+/- in about 30 minutes, these 4x dvd-r discs burn the same 4gb+/- in about 15 minutes!!
Of course you need to ensure that your drive supports 4x media and that you have all the latest patches & firmware updates. I almost couldn't believe a quality 4x dvd-r could be found for about sixty cents a disc without buying them by the truckload. The only complaints I have are:
1. The day after I purchased my 25 pack, amazon dropped the price a buck on the 25 pack and raised the price on a 100 pack by about twenty bucks.
2. The top of the discs have the Ridata images & logos etched on them.

Summary: ridata is just plain poor quality media
Review: I ordered ridata 4x dvd-rw and ridata 4x dvd-r, and im dead serious when I say both batches of discs were corrupt. However crazy that is, the quality of ridata labeled media is the same as the garbage you bring outside. I have a pioneer a05 and the discs are not even recognized by any software in the drive. When I burned the 4x dvd-r discs, I had like 4 out of 5 coasters. Ritek used to make quality and affordable media, but this ridata labeled media is just plain junk, avoid it. Look at every else reviews, its no secret that you shouldnt buy this stuff.

Summary: G04's are some of the best media
Review: I've burned about 100 of these without one error, either in the write process on my NEC-1300A, nor in playback on my computer or in my cheapo Toshiba dvd player. I use fast forward and rewind a lot, as I'm an impatient movie watcher, so these have been put through some hard work. I had some problems with Memorex media, but then I read the reviews on videohelp.com. Hundreds of customer reviews are listed there, and you can match your exact burner to exact media for reviews of success and conpatibility. Ritek (or Ridata) G04's like these routinely get the highest ratings. They are in a class above any blank media you are likely to buy off a shelf in an electonics superstore.

Summary: Works FLAWLESSLY with Apple G5 dual 2.0 Rev B
Review: I've gone through 125 of these DVD-Rs by Ridata, and so far the burn success rate has been 100%. Not only did the burned discs play in my Apple computer, it also worked on two other DVD players (a Sony 5 disc DVD player and a Toshiba SD1200). I burned my discs using Apple's iDVD software which came bundled with the computer; While burning, I even used the computer to surf the web, and noticed the DVDs were burned perfectly without any problems <although that's probably a testament to the awesome G5 rather than the Ridatas =)>. I'd highly recommend them! (I just placed an order for another 50!)

Summary: Slow and Bad
Review: It can only burn at 1x-2x that used with RecordNow and at 2x-4x with Nero6. And I have also found 6 bad disks so far after 12 attemps in which 4 of those I can physically see the scratches and purple spots hidden behind the surface. the reasons i gave it 2 stars because of its price and spindle box instead of in cup cake oem version like other online sellers. Honestly, I've been sucessfully burned with 4x with very low % disk failure with Ritek before where I got them as an oem cupcake version. And don't get me wrong 'cause I could be an unlucky one with this spindle...

Summary: Useless for Sharp DV-SR3U recorder
Review: The Sharp DV-SR3U recorder gives error message that it is unable to fix these Ridata disks and rejects them. Fuji disks have recorded flawlessly.In past I have used the unbranded matte Ritek disks successfully but I do not trust this Ridata product.
