I have just built a HTPC system with the following specs: AMD 64 3200 cpu ASUS AV8 Deluxe mobo 512MB PC3200 RAM Radeon 9800 pro I had run TT2 with ffdshow on my 2500 Barton clocked to 3200, running the Blur and NR and resizing to 1280x720 Lanczos 4. My CPU usage in task manager was in the 90% range so I decided to upgrade to my current specs. I have installed XP sp2 and have no other software installed other than TT2 and ffdshow. I am using the same settings as my old system and I am hitting 100% cpu usage now The problem seems to lie with ffdshow, without it running TT2 uses very little cpu and windows media player maxes out the cpu when ffdshow is installed. I have tried re-installing ffdshow, both the normal and sse2 versions (sse version always says a file is missing when installing sio have not tried that). Can anyone help me to get this problem sorted?
