Update: they freeze

Did you download the "Fixed" versions or the originals? The original Hyperspace set had a tendency to lock-up in some players (including my own after a time).

The only other suggestion I have is to download the MKV versions instead and convert them to AVCHD...or just play them as they are. The video and audio streams are identical, so there's no drop in quality.

Sorry to everyone who's had so much trouble with these. I honestly have no clue what the problem is. And, from what I can tell on my own BD player (also a Sony), the "fixed" versions are working fine :/
