Hi everyone,

sorry for bad english, but I hav to give it a try. A friend of mine has tryed yestarday to play a burned dvd with couple .avi-s on a laptop. The Windows has frozen and he has just turned the laptop of. After that the dvd couldn read any cd-s or dvd-s more, but windows does stil recognize it. I´ve tryed if I am gonna be able to boot from the dvd-rom with a bootable win xp cd, but that havent work. I´ll appresiate any help.
