I am going to Tell you the easiest and the most convenient Way Of making A jatg rip, Either Of an ISO, Or from a DVD.
1) Making Jtag Rip from Iso:
First, Download XBOX IMAGE BROWSER:
Then Open It and Select IMAGE BROWSER
After that, Select ISO file and Extract it, After its Done, Open the Folder and Delete SYSTEM UPDATE folder, And if you want to make Rip Even Smaller then Delete All other Languages Except English, Plus Delete all other Crap Files You find
Then, Just Copy Folder Into USB and then Play From DEFAULT.XEX File.
2) Ripping A DVD
Download the latest XBOX BACKUP CREATOR which supports XGD3
Then Open it and select IMAGE BROWSER, Then Select OPEN DVD From top Left Corner
Afetr that, Extract all files and then Do the same steps as told before In the RIPPING ISO above, IE. Deleting system update folder etc
Then Copy Files and transfer to xbxo and play with DEFAULT.XEX
