I have read many forums regarding the ability to display UMD quality video on a PSP, using the memory stick. It seems like the most knowledgable people recommend the kludge of using 368x208, and then zooming it up to 480x272. Why? UMD video looks so much better than the 368x208 compromise. Clone DVD Mobile has a script which allows: [PSP Patched (AVC/H264, Ver. >= 3.03 OE-B)]. When I tried it on my PSP ver 3.51, it did not work. So I searched the forums and found out that ver 3.51 is S.O.L. for native video. So, I decided to hack away at the cDVDm script, and, Hello Nelly... I figured out a way to encode 480x272 @ 8Mbs. Looks better than UMD, in my opinion. You need a 1-2GB stick for a movie, but the quality is astonishing. Just curious if this is something of interest to others? H.
