Hello,
I think I have a problem with my burner and/or laptop.
I have a Compal FL90 notebook.
I use stealth-checked / verified isos only, and the burn process completes successfully (without errors / warnings except Duplex Secure's SPTD).
When I put the disc into my xbox, it works, but after a short while I get the error 'Please clean your disc'.
When I check the dvd with abgx's 'burned dvd' option I get a game crc error at approx. 50% (at the layer break).
I assume it's not Verbatim's fault, but maybe lacking firmware upgrade (if it exists for Compal) or those sptd drivers?
Or maybe Alcohol 120 / Nero software is in conflict with ImgBurn?
Has anyone of you had a similar issue?
Please help, I've wasted enough discs already

My friend had the exact same problem. Disks would stop working and abgx gave the CRC error at the 50% mark (layer break). After burning the same ISO using the same media on my desktop, we realized that it was his burner that was giving the problems (firmware upgrades didnt help him). He decided to use his desktop for burning back ups and replaced his 8 year old burner with a new LiteOn iHAS424 burner and has never had a problem since then. So if you have a desktop around with a burner that isn't ancient, try using that.
