So it's a small change you can do yourself fairly easily, my real intention is to speak to the Mpeg-TV people to add this reception functionality into their application, since basic RTP is not that hard to do. (and MPEG-TV is definetly the fastest software decode for MPEG I've seen on intel architechtures, not counting some unreleased MMX-boosted stuff that are not generally available) Pete
