I'll post my test results, I use a sharp Aquos LCD HDTV:
For PS1 I tried FFIX, and RE2. They both looked good better than I remembered them especially both FMV's.
For PS2 DMC 3 special edition looks really really good in game + cut scene for me because of the output ted 480p. FFXII was sort of a mixed bag the FMV was wierd with minor glictching but the regular in game looked slightly better than on ps2, but on my TV non progessive scan games like FFXII usually look bad.
