There are some problems playing BD disks with MPCHC. For one, you don't get the menus. It never worked well for advancing or going back by chapters either. When I try to advance to the next chapter, it simply pauses.
But it will play the main movie straight through if you don't interrupt it. Usually. If it doesn't start skipping, or having trouble with split m2ts files (seamless branching structure).
Haven't heard of Splashlite, so I'll have to check that one out Ricoman.
