I remember there are a lot of EBU feeds on Eutelsat W2 that use MPEG
4:2:2.
See http://www.lyngsat.com/ew3.shtml for details.
As my system is currently very unstable (mb problems) I can't use the
DVB card for anything.

If anyone on the list could record something from those feeds...

Although I don't know for sure how accurately will comply to the
standard, but I know TMPGEnc can create MPEG2 4:2:2 files. I was able to
play such a file created by TMPGEnc with Elecard's MPEG2 player.
Of this I can upload a sample file tomorrow maybe.
