I was all ready to watch this tonight, and now I have a problem. I watch MKV by putting it on my portable hard drive and playing it through my Blu-ray player USB. I have a PC laptop, but I wanted to download this on my family's MAC, since I don't like leaving my laptop on all day. So it finishes downloading, and I put my portable hard drive in to transfer the file, and it can't be done, and shows the hard drive is read only.

Anyway to get by this? I guess I'll have to buy a BD-R, and burn it as data disc to transfer to my pc?
