I2C is driven by open-collector outputs, so you can hang extra devices on it - including controllers. The chip will decode just about any video format you could want - but it has to be told which one (some of these chips will detect the standard, and tell you, but you still have to switch it to a particular mode). So it should be possible to build a little add-on that waits until the chip is initialised and then writes a new configuration. I2C is easy, and the datasheet (freely downloadable) tells you everything you need to know. I forget the start of this discussion - did you want to change the input or the output format?
