In my experience, if you want to use BD without any issues, you need to install it on a clean Windows installation (or clean system image). But I must be honest that BD does not always work flawlessly on every device. Some friends of mind were never lucky with BD. One more thing, if you have 4 GBs of RAM, it is better to use sth else.Yeah well said. I hope no one gets discouraged by the issue that I mentioned. If someone has no problem with these very specific things then great. It's a great product with very good all around performance.
