When i copy a dvd it will not paly in this player. but it will play in other players . why?

the region is not set

If it was a home made disk then your problem is not with the player but with the burning software and or method used used.

If it however does not play a store bought dvd then there will likely be an issue with the player itself

Triyng clean the laser lens

1. Press the "menu" key
2. Press the numbers 1,6,7,1,9
3. A menu should appear on the upper-right corner of the tv screen asking which region you wish to play
4. Press the number of the desired region ( 0 for regionfree ), wait a second or two and you should be able to load and view the DVD

well.. philips dvd 622 is a good dvd player.. but it won paly any pirated versions of dvd's ..though u download it from net..check for the good versions. also check whether is a rip or zip file k.

were you able to play copied dvd's on this unit ? if yes then check setting on the dvd menu for things like DVD REGION and DVD playback speed and types of DVD playable, this is quite likely as i ha this problem on a pioneer model previously.

do those copied dvds no longer play on the same unit ? and you have tried them again on another unit or dvd player ?

rather i suspect problems with the DVD burn itself and its compatibility with the dvd player you are palying them on now (asuming settings in DVD enu are correct as loosely outlined above in point 1)

it may be that if this is a new dvd player than the one you played them on before, the dvd's may have to be closed in a certain way using your burning software so that they are playable on standard dvd players.
please also check that region is not an issue and that the recording speed of the dvd (the rip speed) is not too high or too low for your unit, as this data is stored on the written dvd and is responsible for the quality of the palyback data.

When passing the video signal thru a VCR on the way to the TV, you are activating the DVD's "Macrovision" copy protection.  You need to hook it directly to the TV.

I had a similar problem on a different DVD player and found that if I plugged it into the TV the problem went away.

this may be the problem with your dvd player
