Sony DVD Update

I have got a Sony DVP-S536D DVD-Player, but
don’t play CD’s and VCD’s, they are not original.
I think, I need a Software-update to solve this problem,
but I don’t know, where I Get this Update.
Please, If You can help me, do this!

Is this a stand alone player, or one in your PC?

Some stand alone players are known for not being able to play backups. I seriously doubt that you can change the firmware of a stand alone player yourself and even if you can, that it will solve you problem.

If it is a DVD player in your PC, I doubt you can fix this (what appears to be a hardware problem) by changing software. It is, however, easier to update firmware for PC DVD-player…but if it will help, I doubt it…
