If you want to measure the overscan, I've put a test VCD file at http://crusty.lsmo.sytes.net/video/
There's PAL and NTSC types. Magix Video Edit Pro 10 came with a ready made project for this, I used it then measured my own TV, a 25" cheapy Emerson. and it was 14%/16% horizontal and 16%/18% vertical. I need to make a linearity test pattern too. I'm sure it's got a pincushion error too.
