I think you're wise to go with Verbatim.
I have another follow-on regarding the bad TDK "Life on Record" media:
In trying to return them to Amazon, Amazon refused to take them back because I had had them for longer than the return window (which is often the case since I don't break open a new package right away after receiving them). I can understand that.
Given that, I sent TDK an e-mail describing the problem and asking if a refund was possible. In reply, they asked for information on the DVD deck I used, my operating system, how many failed, etc.. They also asked if I had applied any firmware updates to my DVD deck. I replied with all the information requested, and told them no firmware updates had been applied since the deck had no updates issued (my deck has only been out for a little over a year and Panasonic hasn't issued any updates).
The next e-mail asked me to try the bad discs on another deck (which I did on my Sony deck with the same bad results). In their next e-mail, they suggested the discs might have an "incompatibility" issue and their warranty didn't cover "incompatibility" since DL media is subject to a different set of manufacturing & compatibility rules relative to single layer media????? I really didn't care since "incompatible" meant "doesn't work" to me.
At that point (about 4 e-mails and rising), I politely replied that it was apparent they were stonewalling with no satisfaction to my claim in sight, so I was simply switching over to Verbatim (which I had already done and had excellent results with the Verbatim DVD DL media). Then I got one more e-mail asking if I had done a firmware update (DUHHHHH) and I broke off contact with TDK.
It's amazing that a company like TDK changes their media from good to bad, and then offers "customer support" whose only job is to stonewall and put the blame for their bad media on the customer implying I have two "incompatible" decks which don't handle their media (although their previous batch from the Ritek source worked great on both of those decks). Not only did they lose one customer (me), I can assume they'll lose many more as word spreads about their DL media issues and customer support.
Someone in their corporate offices is a bean counter who made the decision to switch suppliers and make a bit more profit, when in fact, that move may ultimately cost them significant sales. Unfortunately, this seems to be a trend nowadays and the customer suffers for it.
Bottom line: Go Verbatim (and hopefully Verbatim won't do something as foolish).
