Thanks Devra, Strange thing is my computer is also new, (only a year old) my monitors however are all hand-me-downs, but i did have the monitor hooked up and working fine, then i unhooked everything to move my computer and a little after i hooked it back up this problem occured, mybe something happened when I took them apart? but when I use my main desktop monitor for playback it orks find, but not when i use my 2nd monitor for a preview monitor. also the video again does come up when I go to show current but once i play the clip it goes to white and i get only sound, also i recall playing with multiclips and show multi angles when the problem occured, maybe that has something to do with it? and now recently when i played my timeline i noticed it was freezing and playing back very choppy, as if theres dropframes only theres not, and only on the computer monitor this happens, on my tv it plays smooth, any ideas what thats about? i havnt really looked into but i noticed it when i was exporting something in a rush to dvd so i didnt really look into if this is something i could fix but any help or info i appreciate. Thanks
