Dvd "Highlander DVX4533 " no sound

I don't understand your problem.
Is it the TV or is it the DVD? You say you tried other dvds and the problem is still there. Looks like the TV is the problem. Sometimes it's hard to help people when they only mention on screen issues. How can first DVD say 'incorrect disk' and then another dvd, and another still say 'incorrect disk'? It just doesn't seem to make sense. Is the contents on the disk a computer recorded movie, film or home movie? If so, you have to record the film on the disk with a format that accept the DVD. Could the DVD be a Blu-Ray, can it play a number of video formats, DVD, DivX, KviD DVD, etc.? Try first with a purchased movie DVD disc, if it doesn't work, then the DVD is faulty. DVD players these days are meant to play a wide range of video format, including CD discs. If you have an old DVD player, you may not play latest discs. But if the DVD is incorporated with the TV, then you have to insert a new movie and see if it plays. Go to an appliance or TV DVD store and talk to them. Or you can purchase a new movie and insert it in. If it doesn't work, you can always return it. As you said, you've tried different DVDs, sounds like it is a separate DVD player. If so, try other movie discs. I get the same warning only when I insert discs with movies I recorded on my computer, such as Pinnacle video editor.

Try this

1.While the previews are playing, press the Menu Button on your DVD player remote to access the DVD's Main Menu.
2.Go to Scene Selection and press your Enter or Ok button on your DVD player remote.
3.Highlight Scene 2 and press the Enter or Ok button. This will start the DVD in Scene 2.
4.Use your rewind or reverse button on your DVD player remote to rewind back to the beginning of Scene 1.

check colour system settings - NTSC or PAL what is your tv normally using - check DVD PVR6000 has color system on matching TV color system.
Can't find the user manual online as the specific make and model number were not given for the device.
if you google search or yahoo search for
{make} {model number} user manual
{make} put what the make of dvd player is eg highlander
highlander is my guess and my guess of model number is DH-2816 but it is only a guess .

Please check the read surface of the disc you have already played on this player. Are there circular line on the surface. Best is to remove the top cover and observe if any foreign objects like sticker or paper is lodged in the loading tray. Also play with the sound off and see where the sound is coming from.

you need to install proper codec for this so go online and download codec pack

Bought a new unit. The old unit was a surround sound system in which the previous owner removed the speakers. I wasn't aware of the problem but found out that it would not allow it to play on Dolby 5.1...It would only play DVD's on channel 2, therefore no english etc. Thanks for your help!!!

Ive just had the same thing happen to my highlander dvd/hdd 160g.
Mine lasted just over a year and I have lost the sound as well. It worked perfectly and No problems until sound suddenly disappeared

This was probably caused by an update,just reinstall your DVD encoder/decoder software.

You can not view from the USB, since the USB port on the DVD player is ver 1.1. The transfer speed is to slow to watch a movie. Alternatively you can copy your movie from your flashdrive to the harddrive and watch from there. You will see what I mean with slow speed when you copy the movie. It takes ages.

If it is a blue ray, you need a blue ray dvd player.
