Is anyone else having trouble playing the LOTR 4 disc extended cut in a PC DVD-ROM drive??? My LG DVD-ROM DRD8160B (6 months old) can't read any of the 4 discs, gets a "Error Code 89030000 : Unknown File Format error". I'm using PowerDVD XP and WinDVD 4 under Windows XP. Even Windows Explorer doesn't work!!! It's never had any problems before and usually reads everything I throw at it. My temperamental Sony 735 and cheapo Samsung 807 DVD players can both read the disc with no problems (other than the odd C:13:00 (which the Sony player always gets on all my discs). The discs have DVD-ROM content so why can't my PC read them????
