PC and Mac

What is the best Blu-Ray Disc software to get for the PC? I have a BD-Rom but not the software for it. I know of PowerDVD but I haven't bought from them before. Any one have experience with them or think an alternative is better?  
 
Much thanks. 

I only have experience with power DVD in terms of blu-ray playing but its fairly competent and does what it needs to do fairly well. I can't believe there are no free alternatives yet buying a laptop with a bluray drive then finding i have to drop more money on software was not fun.

Yeah, no doubt.
