I have a aspire 8930G with Blu-ray which played Blu-ray DVds normally. Lately it will only play normal DVDs, detecting them and automatically starting acer Arcade and playing them. On putting in a Blu-ray however it only opens a window on the desktop with a folder of the files on the disk. If I start Arcade manually with a Blu-ray in the player and click on Play it waits about a minute and asks me to put a disk in the player. i have tried all the options in Windows Autoplay, such as Always ask etc, none of which seem to make any difference. I have access to a similar machine and compared drivers etc and there does not seem to be anything different, the other machine plays Blu-ray and just appears to have the same driver with no dedicated one for Blu-ray Have uninstalled the dvd drive and let Windows reinstall, no difference, looked on Acer site for any patches etc If anyone can make any suggestions I would appreciate any help, it is out of warranty andbeing broke I could do without having to pay some shop [b]Since writing the above I have downloaded and installed a trial version of an independent Blue ray player, this detects the bluray disk and plays it. It was CyberlinkDVD and also downloads a program to see if your laptop chas any problems with blu-ray, I had to update my graphics and when done it gave a clean bill of health The point I am making is that despite the indepenfdent program detecting and playing Acer Gridvista still does not see the disk, Does this mean it is a software problem?
