Playback Questions

Q:Why does my AC-3 audio sometimes pause or pop when I’m playing movies?

A:Windows 95 supports background processes, which are small software programs designed to improve performance of certain applications or perform other functions without requiring you to

manually launch them. These background processes can sometimes interfere with continuous processes such as playing audio and/or video which have specific requirements for sustained data rates. These applications should be disabled whenever possible. Examples include screen-savers, anti-virus software, fax receive and answering machine software, Microsoft’s Office95 Fast Find, etc.

Q:When using Windows 95 MediaPlayer to play standard MPEG-1 or MPEG-2 video files, I sometimes get thin, hazy lines along the left and bottom edges of the video display; why?

A:Most MPEG-1 and standard MPEG-2 content is not as carefully produced as DVD titles, and it is possible for these thin, hazy areas to appear at the extreme edges of the video content when played back. This effect should never be visible on professionally mastered DVD content.

Q: Why can’t I play encrypted (*.vob) files with MediaPlayer?

A:Media Player does not initiate the Authentication process necessary for an encrypted DVD stream to be decrypted. Attempts to play these encrypted files (with .VOB extensions) will result in no video played. The authentication process is initiated in DVD Player, which should be used to play all encrypted content.
