Please pay attention to this simple checklist before posting a new bug entry:
Please include all information that seems to be relevant to this bug. This usually includes the xine version, the audio/video drivers being used, an URL of a sample stream or something.
Logging in to a Sourceforge account is highly recomended before posting bugs. Unless the bug is deadly obvious and doesn't need any contact information, it is likely to be deleted due to lack of submitter contact.
If you are uncertain about any of these points or you have any questions that do not necessarily classify as a bug, you can always contact the xine-user mailing list first.
