[DCP-o-matic] Playback issues

hello, I recently created a DCP of my short film, but when I play it, the video stutters by a LOT. I'm running a high end PC (Windows 7), playing the file off a SSD. I'm trying to figure out asap if its an issue of my PC, the player I'm using or the DCP file itself. The player is called DigitAll DCP Player, and I'm awaiting a response from them on the issue. If its only an issue of the player, I should be fine since I'm sure the venue at the festival will have good enough hardware. If it's an issue with the DCP file though, I really need this figured out in time for next week. Thank you!
