Even when the audio file itself does not contain undesirable gaps, software, firmware and hardware design often add gaps during playback. In some cases, software closes and re-opens the output stream when switching tracks, causing the hardware to create a very short "click". This problem is solved in more sophisticated designs of gapless playback.

A different design problem relates to software/firmware/hardware which are not ready to seamlessly move to the next track by the time the current track is complete. In this scenario, the listener is left waiting in silence as the player locates the next file, reads it, decodes the first blocks if necessary and then starts loading the buffer for playback. The gap can be as much as half a second, or even more — very noticeable in "continuous" music such as certain classical or dance genres.

Many older audio players on personal computers do not implement the required buffering to play gapless audio. Some of these rely on third-party gapless audio plug-ins to buffer output. Some newer players and newer versions of old players now support gapless playback directly.

I would appreciate this autorun feature. For Example, Tvix 6500, have the possibility to create a folder named "AUTORUN" on the inside HDD. On that folder you can put what kind of files you want, i used it for music, and it plays. The good reason it's that you can listen to your favorite music without open the TV. So i am wondering why something like this cannot be applied also on WD. I power the media center and it starts to play from my usb device all the music i have in AUTORUN folder, in random mode. COLLLLL. PLSSSSSSSS add this function in a future firmware. Thank you!
