Will look into the reported problems for the Bt848  driver.

One thing to bare in mind about clipping is that the driver will require
some sort of compiler or generate the program in user land and pass 
it up to the driver .

With respect to DTV,
Again, the Bt848 executes a program in the host memory so to do 
arbitrary clipping a program will have to be generated to do so.
By itself this is not to much of a problem;however, when moving
windows around it can be a problem because for any geometry change,
the bt848 must be stopped, the program generated, the registers
reset, and last but not least kick off the overall capture process.

So if anyone cares to implement clipping please post your algorithm
to the list for review.

Last but not least have fun guys !
