OK, what am I doing wrong???

OK, I have a modded Xbox with Xecuter2, I've been able to connect to it from my PC using FlashFXP, I've downloaded every program I found referenced on this site and I STILL cant figure this out.

What I'm trying to do (if possible) is insert a game disc into my PC and get it into my Xbox in a playable fashion. The Xbox CD drive will barely read anything anymore and I want to install some of my games on there to play them.
I've tried using DVD Decrypter to get it to an ISO (game in question is Tiger Woods 04) and did so, however it came out as two files, one .ISO and one .MDS (believe it is a dual-layer game disc, DVDDcryp said 2).

Now I'm not sure what to do, everything I read says it has to be filed into the Xbox PRIOR to being copied or pulled onto the PC. Is there anyway to do what I'm trying to do? I've tried swapping CD drives out of the modded Xbox with other Xbox's, but they all suck. The game is barely scratched up even. Can I pull a drive out of my PC? I'm not a total nooblet but there's alot I dont know. Can anyone help on this one?

TIA, Zelen

 

I'm pretty sure that the pc can't read the xbox disk. If you look at any procedure for backing up disks, you start with putting the disk in the xbox and then ftping it to the computer then using specific software create a xiso and then burn it. There are ways to fix the drive issues you have. Just find out what drive you have and then google it or look in the pinned section of this forum for information.
