Hand sketching on videos and recording this (Windows 7)

[Opusbuild]

Hi all,

I all, I have a Wacom style tablet (Aiptek) and I am trying to find the best way of annotating on the video video live whilst recording this. I have tried playing the video in windows media player, using a program called Epic pen (http://epic-pen.com/) to annotate over it whilst the video is playing. Then recording that section of the video using CamStudio. The only problem is that the annotations using the tablet is lagging, it seems fine when I do the annotations with the mouse. I don't know if this is a tablet issue, graphics issue (only have HD4000 on board graphics). Just wondered if anyone has any other ideas.

Thanks

Have you tried another USB port to rule that out as a potential issue?

Do you know someone with a different tablet you can try?
