Downloaded PowerDVD 21 to play avchd and BD created with PowerDirector.
It will play avchd on DVD+R 720/60p.
It will not play avchd on DVD+R DL 720/60p.
It will not play avchd 2.0 on DVD+R DL 1080/60p.

It will play an avchd 720/60p folder, avchd 2.0 1080/60p folder, BD 720/60p folder, and BD 1080/60p folder on both flash and hard drives.

Upon playing low bitrate avchd and BD material on discs or folders created with PowerDirector, the video and audio freezes every few seconds and then continues continuously like a stutter after video lengths of 90 minutes and greater. These low video bitrates are say 2800 Kb/s to 5000 Kb/s which is good for a 10 hour BD. Increasing the bitrate to 6000 Kb/s does not help.

There are users who claim to create 20 hour BDs material in the PowerDirector forum. I was hoping that there is a player for this. Has anyone had success so far...
