One other way is to convert the main movie to mkv. (Download MakeMKV from
MakeMKV - Make MKV from Blu-ray and DVD - All features (including Blu-ray decryption and processing) are free during BETA ). Install Shark007 Codecs to play mkv files with WMP/WMC .
While purchasing the blu-ray drive itself one should check that it comes bundled with blu-ray player software so that he/she need not go through this exercise.
In any case, since you have purchased a blu-ray drive, you should plan to get Power DVD 10 Ultra 3D Mark II which at the moment is the ruling king. ( Tip: I bought it from Major Geeks
MajorGeeks Software Store where it is a little less than direct Cyberlink store price. Keep this in mind whenever you decide to go for it. It is genuine with direct download and key from Cyberlink.)
