@ Josey (The Outlaw???) I can say with 99.99% certainty that your problem is that you do not have the UDF2.5 reader driver installed. The way Blu-ray discs are burned using the UDF 2.5 file system, XP doesn't come with a UDF reader, so you need to install it. Follow the instructions from the Slysoft link above. There is a reference to BD 2.0, this is just Blu-ray's version and has nothing to do with drivers. BD 2.0 I believe is when "BD Live", or BD+ was introduced... I'm not to sure. Your LG drive has the latest FW (YL05), which is good. It also plays DVDs so we know it functions properly, it just doesn't read Blu-ray discs, I am confident your issues is the absence of the UDF 2.5 reader.
