Stefan:

You should check the 'video processor' section in the AVSForum - lost of discussions on this particular scaler. Although I am not certain, I think I had read some time back that this unit does not de-interlace 1080i properly; but if you are planning to use it with a SDI modded 598, then you probably only care about 480i.
