Portable DVD palyer

Since you are able to view the video then I doubt this has anything to do with the disc type or the mechanism. The data stream is clearly being read from the disc.

Please cycle through the audio language settings.

Although I don't know this player, sometimes DVD [discs] come with more than one audio track to cater for different dialects and maybe you are listening to a blank track.

Hi lsecrist...I regularly see this particular brand exhibiting random acts of blindness. However, to remain fair and unbiased, we really don't know what editing process those incompatible DVD's endured. So, if you'd like to just convert your player to Region Free, turn on your player, and using your remote, enter the following commands: 1) Menu 2) 1 3) 9 4) Highlight "Region" 5) Enter 6) 0 7) Enter 8) C Keep in mind that although now region free, this will not cure all of your DVD woes for this player. However, it will certainly give you a vastly greater range of DVD compatability....Please update your post whether positive or negative so that I know whether I should get a bigger hammer or not....good luck my friend

Getting a signal from a DVD is a very complicated process, involving bouncing a laser beam off of the DVD, digital electronics, microcomputers, & sophisticated programming. In this tangle of signals & programming, it is not uncommon for a glitch to prevent the player from performing correctly. There is nothing wrong with your player, per se, except that it glitches on those particular discs. The solution is to simply not play those discs on that player. This phenomenon has happened with every optical storage device since the very first laser disc player. Some players simply don't like some discs. You can try a lens cleaner disc, but it is unlikely to make any difference. This problem is just an aspect of the technology, & is not going to get any worse.
