Ridata DVD+R Double Layer 2.4X (5 pieces) + DVD+RW 4X (1 piece) in gift box review:
1 stars (Very low quality. Beware!) - I've bought this package, and out of 5 disks, 2 ended up in trash. One won't read in the same drive that burned it, and the other one has massive CRC errors. I tried Verbatim DL disks, and they burned without a hitch.
3 stars (Good burns, but player compatibility isn't the greatest) - I bought 10 of these Ridata DL and each one burned fine on all of my drives (a wide assortment of name brand drives). But the finished discs did not work very well on quite a few of my standalone DVD players. Some players handled them fine, some would only read the 1st layer and freeze while trying to switch to the 2nd, and some didn't even recognize the discs at all. I've never had a problem with any Verbatim DL discs before, they've always burned well and played perfectly on every single player I've used. But these Ridata DL discs aren't as versatile, at least in my case. If you can spare the extra few dollars, try to go with Verbatim DL media instead of Ridata. The 2 or 3 dollars saved is meaningless if you can't play the discs.
5 stars (Ridata quality) - I'm using Roxio 7 with a NEC burner and have no problems playing these disks in my PC or Home theater system. These disks are great for the price.
