The last batch of 50 pack Ritek G04's which had "Version 2.0" printed on the top among other text (not the old red/white packaging, these are in the blue and some other color wrapping shown @ Newegg and Shop4Tech), would only burn at 2x on my Sony even though previously all I had purchased before in DVD-R media were 50 pack Ritek G04's in the red/white packaging which they don't make anymore in DVD-R format. I was very dissapointed in that, the discs are fine but the reduction in burning speed was cut in half which did not sit well with me and I vowed to order a different brand/make next purchase. Even though I had no bad burns or inconsistent looking media in this new pack I couldn't see buying Ritek G04's again for twice the price of the Sonics. So I'm ordered 100 of those to try out but I agree it's probably a crapshoot right now unless you buy Taiyo Yuden, etc.. I won't pay over a certain amount per disc however, it is not that important to me since right now we are only buying 4.7gb single layer discs anyhow. It would be a different matter if the discs were able to store a full movie without compressing from dual layer tp single, I'd be willing to pay more for quality brand double layer discs once they settle down. It is still a matter of how important your backups are to you I suppose. Some people are willing to pay near $1.00 per 4.7gb DVD-R but I would not pay over .40 cents at the moment.
Just to some it up, I strongly believe Ritek G04's have gone down in quality to some extent lately. Although I have still not had any bad burns or inconsistent looking media yet.
ReiAyanami: The non-free version of DVDInfoPro has a way to check for errors on DVD media. It's a very nice app indeed. Be careful which version you download, one is the free version which doesn't have a lot of features like the error checking and one is a pay version even though both have "Pro" in their names. I believe you might be able to run an ad-injected version of DVDInfoPro without paying and get the full functionality although I'm not sure. It also shows the full media id code of your CD/DVD discs.
