I have burnt around 30 DVDs 3 years ago on Princo DVDs. All of them are still working fine. Just that they are still rated at 4x. There used to be a brand called Unique, which were MBI produced and used to sell for below 15 bucks for 16x +R. You can check the manufacturers in programs such as DVD Decrypter. But, those are no more available.
I wud suggest to buy Moser Baer "Pro", and not just Moser baer. The pro series are not suppose to sell in India and is to be exported completly. But, you still do get it here. However, they cost 1-2 rps more than just MB.
