Hah, the truth comes out.
Anyways, assuming your Lexus's drive isn't becoming flaky, an easy solution is just to buy top quality discs (eg. the aforementioned Taiyo Yudens), and then burn them at 1X speed.
98% of so-called drive problems have to do with people buying poor to mediocre media, and/or trying to burn them at 16X.
Also, some of the older drives prefer DVD-ROM or at least DVD-R. You can buy DVD+R drives and flash them so they set the DVD type flag to -ROM. If they see +R they freak out, but the same +R media flagged as +R works fine. However, that doesn't sound like your problem.
