This won't be much help but a few mins on google and I came up with this:
1. It depends on the blu-ray player and what formats it will play and what formats are on the card.
2. There are SD to USB adapters (I have one that I use for my digital camera card).
So basically you could by the adapter, put it in, only to find out the player won't recoginize or won't play it that way....it's seems like it might be a crap-shoot as to whether it will work or not.
