Set top DVD player plays VCD and music CDs but not DVDs

[jbirdg]

I have a Qwestar (Oritron/KOSS clone) DVD player that plays VCDs and audio CDs just fine. The problem is with DVDs. It will play a DVD for any where from 10 secs to 3 minutes and then freeze up. It will then say invalid disk for every DVD I put in it after that (but still play vcd and audio). I have to unplug the power for 30 min before it will even try to play a DVD again. I have tried to clean the lens but no help.
I would think since it play VCDs and Music CDs that it is not a mechanical issue.
Has anyone else seen this problem or does anyone have any ideas?

Thanks,

Commercial DVD's or DVDR's?

It could be a mechanical issue because the laser that reads VCD and music CDs is not the same laser that reads DVDs.

Commercial DVD's.

jbirdg,

If a DVD Player cannot play a commercial DVD Player, then I would suggest you returned it for a refund, or exchange for another player. It's nice to know what's wrong with it, but the main issue is ... this is a "DVD Player" and not a VCD Player that can play DVD.

Cheers,
