...I recently made a recording of myself playing Sega Rally on the Saturn, the DVD recorder I used was a Sony (RDR-GXD500). Now I want to pop it onto either my old iMac (2011) or my Acer, another older device with it's own DVD drive or my Alienware which of course I know I'd need to buy an external drive for of course. Non of my 2 computers with DVD drives will read the disc's, I have made the recording twice; once on a DVD-RW and once on a DVD+R. Strangely the DVD player that recorded to disc's will play them back just fine but the 2 comps see them as either blank disc's or just won't even notice it at all. Equally weird is my other DVD player which is supposed to play both disc mentioned above tries but fails, it's also a Sony. Oh, and the PS3 can't see them either. All I want to do is play some games, record them and upload them... That was the idea anyway so any help anyone can give would be so soooo appreciated! If it's as simple as buying a drive for the Alienware which would be a good one? and cheap? Thanks guys and gals and thank you in advance for not laughing at me.
