I'm going to buy quite a few DVD's soon to use for backup (mostly data, but maybe a few movies etc.. too)and ive got a few questions that hopefully someone can help me out with. 1) Which would be better for my purposes, DVD-R or DVD+R? 2) Are there any guidelines as to which disks have the longest shelf life? 3) Which of the following would people recomend: Taiyo Yuden (4x) Printable DVD+R in Heavy Duty Spindle Tubs of 100 Manufacturer ID: YUDEN000T01 £69.99 Ritek G05 "Full-Face Printable" A Grade (8x) DVD-R Disc in Packs of 50 £15.99 Ridisc (8x) white printable DVD-R in Spindle Tubs of 25 ADVDINFO: TTG02 £6.99 ANV Ritek A-Grade (8x) DVD-R in Packs of 25 ADVDINFO: RITEK G05 £8.50 Ritek A-Grade (4x) DVD-R Disc in packs of 25 ADVDINFO: .RITEKG..04 £4.99 Rivision Overprint (4x) DVD-R Disc in Packs of 50 ADVDINFO: .RITEKG..04 £12.49 Taiyo Yuden (8x) Full Face Printable DVD-R in Heavy Duty Spindle Tubs of 100 Manufacturer ID: TYG02 £69.99 Pack of 5 Verbatim (4x) Pastel Coloured DVD-R (With excellent Taiyo Yuden dye) in Slimline Jewel Cases ADVDINFO: .TYG..01. £2.75 4) Could someone give a rough order of qualty between Ritek G03, G04 + G05 and Taiyo Yuden disks? Are the TY's generally accepted as being better than all the Ritek dye's? And also is there be any variation in quality between the different brands of disk using the same dye, or would all disks using G05 for example, be pretty much identical? Sorry for all the questions (as you can probably tell i'm new to DVD writing lol), but i'm going to be buying around 250-300 disks so i would ideally like to get the best i can, money isnt really an issue, and i'm not bothered if i have to spend more buying packs of 25 to make up the the numbers just as long as i'm getting good disks. I am using a Lite On SOHW 832S drive, if that's of any relevance to what media will suit me best. TIA for your help, NB.
