In some cases, playback may not be possible at all. • When files other than MP3 or WMA files are recorded on a disc, it may take more time to recognize the disc and in some cases, playback may not be possible at all. • Microsoft, Windows, and Windows Media are the registered trademarks of Microsoft Corporation in the U.S. and other countries. 3 Interior features CAUTION n DVD video precaution Conversational speech on some DVDs is recorded at a low volume to emphasize the impact of sound effects. If you adjust the volume assuming that the conversations represent the maximum volume level that the DVD will play, you may be startled by louder sound effects or startled when you change to a different audio source. Loud sounds may have a significant impact on the human body or pose a driving hazard. Keep this in mind when you adjust the volume. 387
