I thought those didn't work in today's players.

In any event, how much time of playback on a BD50 depends on the bitrate used. The minimum that's been used for 1080p hi-def is about 13Mbps using AVC codec + 640kbps for a 5.1 (lossy) Dolby Digital track. That would yield...50,000*8/(13.64*60) = 488 mins, or 8:08. Practically speaking, HD material benefits from using a higher bitrate. If you were to use the full bandwidth every second, there would be room for about 2 1/4 hours of HD video with lossless audio.

Most movies use something in between these 2.
