Reporting a bug maybe?

If you decide to report a bug, providing detailed information is very important. For example knowing whether you are using default nokia 770 player or mplayer is critical. You should also include the information about what software was used for encoding video and its settings. Also some description about the steps needed to reproduce the problem would really help.

Anyway, until the bug is known to developers, chances that it will get magically fixed itself are pretty low
