Lg299h Dvd Hdcp Problem

i’ve got an LG299H HDD dvd recorder which ihas HDMI ouput up to max 1080i and it works to a LCD TV PVision PLD32T .BOTH ARE hdcp.
I ALSO GOT A SONY HDMI PLAYER MODEL DVP-NS78H AND IT DOES WORK TO PVISION LCD PLD32T ON 1080i RESOLUTION WITH ALL DVD DISK.
SOME OF OF THE DISK THAT DO WORK ON THE SONY BUT WILL NOT WORK ON THE LG299H HDD dvdPLAYES IT DOESN.T WANT TO SINK IN WITH THE PVISION BUT WILL SINK IN WITH ANY LG LCD HDTV.
lg SA SAY THERE EQUIPMENT IS CORRECT AND THERE IS NO PROBLEM WITH LG299H HDD dvd recorder.
pVISION SAY THERE EQUIPMENT PVision PLD32T IS ALSO FINE . i ATTEND TO AGREE WITH THEM AS THE SONY DOESN’T HAVE ANY PROBLEM WITH PVISION.
i THINK THE lg IS NOT UP WITH THE hdcp SECRET HANDSHAKE.
HAS ANYONE COME UP WITH THIS TYPE OF TECHNICAL PROBLEM? i NEED HELP?:confused:
