dvd rom

If by "it will read all dvds and cds" you mean commercial discs then there is nothing wrong with your hardware.

Commercial CDs and DVDs are 'pressed' as part of their creation process, in much the same way as old-fashioned vinyl LPs were pressed. The data surface is then coated smooth.

Data CDs / DVDs that are burned on a computer drive consist of layer upon layer of photosensitive dyes, coated onto the data surface. The writing laser in the hardware then 'burns' into this dye, leaving discolouration where the data exists, which can be re-read by the computer drive.

However, in much the same way as an old-fashioned Cassette Tape would play back perfectly on the machine it was recorded on - but sometimes playback would be distorted on certain other machines, it just happens that your DVD Rom doesn't play the discs burned by another machines hardware.

Another disc burned by the same machine or by a different machine may well work without any problems.

Your best bet would be to purchase a DVD Writer of your own and burn discs for yourself. The required data could be transferred from the other machine by means of a suitable Flash Ram memory stick.

Good luck.
