I had a similar problem with my Teac surround sound system $599 v elcheapo dvd player $69.
The Teac would not play anythong other than genuine region 4 dvd's for years.
....until I read an article about dvd player hacks and found out that not only could I now play all disks (and all regions)
but I could turn off macrovision protection by simply entering a series of numbers from the remote .
