a question about the cheaper dvdrs and GTA3

[mac.manab]

As I still consider myself a newbie please excuse any stupid questions that may follow;

recently I have bought a few different unbranded DVDR's some load some dont, some I bought online, some I bought from a local computer store.

the one's that seem to load have wider starting area,ring track what ever its called anyway does this make sense.?

I read the post on dvdr's and GTA3 of course I had this poblem with my cheap DVDR's so do you which brand would be successful?

and finally even if the DVDR's don't boot can make an image file from them and burn them back onto higher quality DVDR's?

that's for any help
