I think the op is asking to do this without using handbrake to convert it or having to use the digital copy etc. The only real way to do this that I know of is with an app like splashtop to remotely access your pc. I have tried it with blu ray rips using my android tablet (actually an hp touchpad with android ported over to it) but it is available for ios. This was playing my blu ray iso's via vlc video player on my pc (power dvd would not work). It works ok but I did have some audio synch issues that I would have to correct every time in the vlc setting to get it to work in synch. It really only works well from within my own network, though it might work okay with a really good wifi source as well. I didn't try it but it should also work directly playing the disk in your computers drive as well, assuming you walk over to your computer drive and drop in the disk of course. You are never going to find a way to play the blu ray files directIy on your portable device, as that would require the device to be able to decode and playback blu ray files, which requires more processing power than any of the current tablets,phones etc have. Even then playing blu ray files wirelessly is not likely to happen very efficiently, as it requires a ton of bandwidth to stream 20ish gb files like that in the first place. Personally, I just take my blu ray files and use handbrake to convert them to mp4 format. They are only a few gigs and look great on tablets/phones. They also stream over my network very well. Of course, handbrake takes time to do, especially with an older computer processor. Hope that helps.
