Cyberhome CH-DVD 300 DVD Player

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.

What kind of DVD player is it? Does it do this with all DVDs?
Have you tried a cleaning disk?

Hi,

Your DVD /VCR says unknown disc because the
dvd which you have inserted is not of the supported format by player.

If you insert unsupported formats only it will say as unknown disc.This is not related with disc cleaners.

Please insert the supported formats and it will play the disc.

Thanx

Try connecting the player to your computer and press the reset button. You'll need a paper clip or thumb tack to reset it. Then remove the clip and try turning it on. Also as a general rule it's always best to insert and remove the clips when the player is turned off.

you may have a region1 player and are trying to play a region 2 disc or vise versa or if you are playing copyed dvds are they finalized.

i used to be able to play dvds no bother but i can only play cds now tried everthing to fix it
