Rune,
I appreciate all the work you have done developing and sharing this program. Really looking forward to the next version of your program when you have fully implemented the "offset delay" feature. It is a useful thing to have when using port extenders (connector savers) or when adding short, quality adapters to a previously calibrated setup. Those attempting to use it to compensate for cable length will need to consider the issues associated with cable loss etc. discussed above and use this feature with caution.
