thank you very much. I was still expecting that and did not get Gordon's point, but must admit to have been totally unaware about the DI/O features. RTD did all the hardware implementations themselves.

BTW, we had the mpeg encoder broken unnoticed for some kernels, but due to fixes by Dmitri Belimov and extensions by Hans Verkuil, we are much better on it these days. Enjoy. Always let us know, if we can do anything or at least make it public for those interested to work on it.
