I need info here. I have always used WMP9 because, one it is a part of XP, and two I like its simplicity as opposed to 10,11,and 12. I found out the hard way that unlike WMP "CLASSIC"(6.4) NO codecs are built into the player. After months of searching I found COLE2K.net. I started with version 7.8 not knowing if it would work. Surprise! then 7.9 up to 7.9.5. Anything beyond that did NOT work. Back to square one. EVERY site that advertised 7.8 attempted to download version 8. Classic "BAIT AND SWITCH" for software downloads! Out of desperation I searched by version number alone. That brought me to KLITE. The site I used did not include a version number, only that it was gauranteed to work with P9. I have heard that lie before. Surprise again! It turned out this was version 9.9.5. Also in the dialog boxes there was a choice to use the pack with either 6.4 or P9 or both. I selected both although 6.4 has NEVER needed codecs. Now both players play both copy protected AND copy writed discs. I added "DVD43" to P9 for the copy write issue. This begs the question why is COLE 7.8 not available, and what KLITE packs work with P9? In the past NO KLITE pack worked with P9. Why does this stuff have to be so complicated?
