Following Peter Osterlund's advice, I upgarded the kernel to V. 2.6.7-rc2. Now I can read *without* any problems CD/DVD created with Roxio's DirectCD and Nero's InCD under Windows XP. Also, unlike with previous kernel versions: There isn't any I/O Error when copying Files larger then 15 MB from UDF formated CD/DVD. So, this seems also to be fixed. Last but not least: Compiling 2.6.7-rc2 kernel, unlike compiling 2.6.6 kernel, was really a straight-ahead job. No problems in compiling the 2.6.7-rc2 kernel, and no problems at all when booting it. I would like to thank Peter Osterlund for his help and advice. Regards, Vlad!
