I've been ripping my home movie DVDs to iso then using handbrake to rip to mkv h264 codec. The video plays fine on my computer but any movement is jerky/choppy on my Samsung LED/LCD 55inch 5 series TV. I've tried using the handbrake default framerate and also 25fps (as the DVD video is in PAL). Could it be something to do with de-interlacing? Any ideas what I could be doing wrong?
