I believe this one is a bug because it happens with MMW only. I am testing currently MMW build 1723 (debug).
There are troubles with this podcast, as an example:
http://tritonia.libsyn.com/rss
(tested with episode 075 and 074)
The podcast downloads an AAC encoded audio stream inside a MPEG-4 container with the extension .m4a. The file contains a JPEG video stream as well with some artwork. I've added MediaInfo output of episode 075 on the bottom for more accurate information.
When I try to move the MMW seek slider in forward direction (-->) while playback of this podcast is running, it has no effect on the audio playing position. It just continues afterwards from the same position like before I moved the seek slider. To illustrate this a little bit, I can move the seek slider close to the right most position and continue playback. Then, the podcast runs to a higher timecode then the real length of the podcast episode file:
Here is the MediaInfo 0.7.71 output:

I can reproduce the issue on my laptop with the same MMW build as well. If I open the podcast file with software like Winamp, Videolan VLCPlayer, the file runs perfectly.
MMW 4.1.6.1723 debug
MM codec pack 2.1.2.105
Windows 7 Pro x64
Any thoughts about that?
