So now that prices have dropped so much and I find myself burning a boatload of CDs for data storage, I'm thinking of finally going to a DVD writer. Since I'm sure there are at least a few DVD burning enthusiasts here, I have a couple questions: -Is there still a big issue with the different formats? I was looking at an LG burner that handled all four, but the HP only used +R and +RW. Is there a major difference in compatability, or media price? -What is a good price on both single write and rewritable media these days? I'm in Canada, so a Canadian price would be preferable. I'm willing to buy in quantity if there's a price break (I buy CDRs by the 50 or 100, so dvdRs wouldn't be a problem). -What's the compatability of the RW and R discs in set top players? I'd like to play around with authoring my own DVDs, but want to make sure that my player can actually read the discs that I burn. -Is there a stated lifespan for burnt discs? People have claimed there is with CDRs, but I can still read the discs I burned back in 1998 just fine. Has anyone had a burnt DVD fail on them? Anyhow, thanks for the information-hopefully Santa Claus (or the wife) gets me a DVD burner for Christmas!
