I use the MPEG capture in animation a lot - only problem I have had is that it tends to run too fast when it is played back using Windows Media Player or Real One. Generally use Snagit now if I'm sending the MPEGs out to a customer because it maintains the same display speed as Pro/E.
Try changing the system colours to "black on white" - View, Display Settings, Sytem Colours, Scheme "Black on White". This will get rid of the blue background and remove the stripes. Improve the shaded resolution - View, Display Settings, Model display, shade, "Quality = 10" and "Show Small Surfaces". Also increase the Frame rate from the default 25 fps to 50 - file size is a bit bigger but usually not too bad.
