Why would it go into Jack CVS? My rudimentary understanding (from a good awful number of years working on 1394 OHCI Link and Phy chips - not software) is that iec61883 is an encapsulation process that places timing info and data packets into a larger chunk of data most commonly moved across, but not limited to, the 1394 bus. 61883 is a really basic way to get MPEG data broken apart and put back together so that you can move movies across 1394. NOTE: There are multiple parts, 6 or 7 now, to iec61883. I'm not sure which ones Linux-1394 is supporting. >From a cursory reading of the Freebob list I have not heard of any special versions of Jack required to run it, but I frankly haven't paid a huge amount of attention to it. Does anyone know? I do agree that this question belongs there. They seem to respond pretty quickly to questions like this. - Mark
