The VideoLAN Forums

This behavior was observed in both 0.8.5 and .6test1, with DVD, M4P, and XviD files.

I'm running VLC on an IBM Thinkpad R31 laptop with Windows XP SP1.

If I start VLC with the AC connected, it plays for a couple of seconds then freezes. If I then disconnect the power, it unfreezes and plays normally. If I reconnect, it freezes again, and so on.

Here is what appeared in the message window in the 10 seconds or so after AC was connected while an M4P file was playing:

If you are connecting and disconnecting power while the media clip is playing and you have issues, suggests a bios problem and you should contact the manufacture for updated bios.

Try rebooting the machine with AC power on and the video should be normal. If you go to batteries do so after shutting down Windows and restarting, everything should also work.

As I recall, there were also some corrections made by Microsoft when SP2 was released that helped some machines this area.
