I do not know of any tools currently available to extract the information. MeTV has a working implementation (with some bugs I have seen), and I was looking at getting it to work in Kaffeine at some point. The spec is freely available here: http://www.atsc.org/standards/a_65cr1_with_amend_1.pdf If you have any questions, feel free to drop me a line. Cheers, Devin -- Devin J.
