Vertical Hold

Isochronous problems sorted, using usblib-1.0 and the asynchronous API.

I now have every line of the field.
Just the problem of finding the vertical blanking period so that I can tell where the top of the frame is.
The 7113 indicates there is a bit field called SAV/EAV that should be setting a bit in the data stream to indicate the VBI, but it seems to be acting screwy.

Obligatory status pic:
Try the vertical hold knob...

Nice progress! I have bought an ezcap unit from dealextreme and it uses the 1c88:003c chipset, so your information is valuable!
