Problem Report: m2ts-Files from Panasonic Lumix LX5

When I play *.m2ts (or *.mts) Files from my Panasonic LX5 under 1.04.17 (11/2010), the following problem occurs:

First three seconds of the video show without sound. Then the video stops an the sound from the first three seconds is heard. When the sound “catches up”, the video finally runs synchronously.

Under Ver. 1.03.49_V and Ver. 1.02.21_V, everything’s fine.

Any ideas? Is this a known issue?

Post few of the Media info of your movies.
