Many people do not like WinDVD and its Trimersion affect. I must now recant and say that the new ALL2HD trimersion is very noticable and improves SD sources extremely well! As a matter of fact - it may be the best upconversion that I've seen. I upgraded my 8 platinum to 9 Plus after seeing what it did for some cheesey SD DVD's that we had at the school board. I didn't go for the Plus Blu-ray because I have two programs that play BD - didn't need it - but the other programs didn't handle SD as well as WinDVD 9 did. Some may not like it, but I'm loving it - alot!!!!
