I have the same issue with introduction of V 3.03.13 firmware. My video files from Panasonic HDC-TM900 camcorder in AVCHD .m2ts ,1080p ,60 frames per second ,25k bitrate are not playing as before. Video jitters and after few seconds completely breaks up. All my videos are on internal drive and I have multiple units in the house and family. All the units have the same problem , and reverting to V 3.01.19 fixes the problem. There is no doubt. By fixing other bugs,the bug for .m2ts files was created.

  1. If push “pause” (mode play), sound is absent, but picture moving  1-2 s (for v. 3.03.13; 3.03.16.). If push “play”, synchronization sound and picture recover at first, then sound go on the run forward from video.

If push Options - Synchronization lips and sound (step + or - 100 ms), but it’s no go.

  1. “Light” bitrate below 26.6 Mbps (for example 1920x1080 50i) problem is absent  (for v. 3.03.13; 3.03.16).

  2. In 2011 the AVCHD specification was amended to include 1080-line 50-frame/s and 60-frame/s modes (AVCHD Progressive) and stereoscopic video (AVCHD 3D). The new modes also allowed higher system data rate than existing modes.
