A while ago I built an HTPC using the IONITX-A-U and just recently I purchased a Panasonic VT25. I have a bunch of MKV files encoded at 24fps and the HTPC refresh rate at 60hz. To play the files I use MPC-HC via CCCP. I would love to watch these files at 24Hz and the TV does detect the signal at 24Hz when I change the HTPC refresh rate to 24Hz but for whatever reason the video is ridiculously choppy. I have all the newest drivers for the processor/video. Is it possible to get this running smoothly? Am I missing something?
