So after a bunch of coasters I finally managed to get cheap memorex media working without any coasters, it took a bit of tinkering but I finally figured out what I was doing wrong. After you get your hands on an image file, you should have a .iso and a .dvd files if you have just the .iso use abgx for all your quality checking, patching, stealthing, .dvd making needs. It's fairly strait forward and already covered in other tutorials. Now specific to Memorex. First off in most tutorials saying to burn at 2.4x, 2x, or the lowest possible speed, they're usually talking about Verbatim discs. Verbatim discs are able to support these burn speeds, Memorex aren't. Look at the packaging, if it says 8x and only 8x, then burn it at 8x. 2nd off use a burning app that supports burning .dvd files *Don't burn the .iso!!!* it has to be the .dvd, I started off using PowerISO to burn the .iso's and in the end the XBox wouldn't recognize the games. Then I tried ImgBurn to burn the .dvd files, but for some reason ImgBurn hates Memorex and would crap out at 50% when switching to the 2nd layer. However PowerISO proved that these discs weren't coasters and it wasn't my dvd drive's fault ImgBurn just doesn't like Memorex, not sure why. So finally I settled on CloneCd which supports .dvd file burning and is able to burn on both layers. Remembered to burn at 8x, and finally I had some playable backups. Hopefully this saves someone from making the same mistakes as me.
