I needed an app to grab stills from a dvd i had made. More specifically i needed it to run automatically on a timer. MacGrab seemed the perfect tool. The timer worked amazingly and i left it for the best part of an hour while the app did its thing. When i went to look at the captures afterwords, not only were they all of the same still (despite all having seperate prefix numbers) but they had this weird kind of black pixel effect all over them. Worse still when viewed in photoshop the portion of the dvd screen was totally black with small white specks!?! Has anyone got this to work or know of an app that will kick it?
