Sorry to post again but this may prove of interest to someone, sometime.
I've been doing some more testing of the the apparently OK AID v4.53 burned disc(s) andwas annoyed to find that they too are unreliable with certain applications refusing to install and on disc tools not launching.
This happens with two different version Xboxes with different make disc drives.
I decided to compare it to my AID v4.4 disc which works flawlessly. It was burned on the same laptop, on the same media and using the same burner: Imgburn (ISO) at x3 write speed.
The only obvious difference is the size of the ISO file. The AIDv4.4 ISO is under 700MB, the AID v4.53 ISO is 1.1GB and that's before I updated it to include all the Addon packs inflating it with the 1GB dummy file to around 3GB.
So I pared that down to the basic Addons packs: 100MB dummy file, BIOS, DHCP patch and XBMC Scripts. Total size reduced to 1.3GB. Burned that exactly as before and, hey presto, everything I've tested works perfectly. Whereas before you could hear the laser struggling to read the disc there's none of that now.
Question is: why?
Just because there are large Addons packs I don't see why that should affect the ability to read the information. The positioning on the disc might be different due to the 1GB dummy file but the layout of the main AID ISO file is surely the same. Access time might be slowed but why any other effect?
The only thing that I could think of is maybe the three Soundtrack Addon packs were the issue. The music they're supposed to play whilst using AID often stopped when clicking between menus never to restart. They're music files are running from the AID disc so they must be using the DVD drive's resources. That must slow it down but would it explain the read problem?
