oh, no @#$@ way...

Two sided dvd-r (4.9 each side) I think is a pretty unsecure way to burn games because then you would need extra care with the discs. And if you are like me that store the games in regular cd wallets (have you seen the dvd-only cd wallets? OMFG lol! just stupid ppl fall for that) they eventually will get scratched on the side facing up.
So if you use those type of discs just to say "I have GTA3 and VC on one disc!" its pretty lame and cheap because my VC is original and it haves some mild scratchs on it and the game frezzes displaying the "error reding GTAVC disc..." thing...
Just get two good dvdrs discs and forget the worries... So what Im gonna do is to burn the VC game on a scratch-free dvd-r

Burn 9.4 on 4.7 obviously cant be done but my point was that there are several brands on 9.4 discs avaiable. just use on a search engine keyword: 9.4 dvd-r and Viola! expensive media and expensive drives w/burning speeds of 1x...

Joy.
