Addressing the disc length issue, disc one felt longer to me (I think I spent 14 hours on it, and about 10 on each of the others). It's important to note, however, that disc three has some bonus dungeons, so it probably has the most length, but this is not main story length.
Addressing the freezing issue, my game only froze twice during the whole 48-ish hours I have put into it, and I ran my game at 1080p the whole time. I also played every disc from the harddrive, so if it is a problem mostly associated with reading from the disc, then I think installing them is the best solution.
