I did some digging, because another site (DBSForums.com) posted that Tandberg received an order at the very end of 2006 for more MPEG4 encoders from DirecTV...
First deal was in February, 2005, for $9 million details here
Second deal was in September, 2005, for $7.5 million details here
Third deal was in October, 2005, for $7+ million details here
These three deals in 2005 were for the EN5990, which was the first generation MPEG4 real-time encoder.
Then, it appears that the only deal in 2006 for MPEG4 encoders was three days before Christmas
. This deal was for the second generation MPEG4 encoder, the EN8090. If there were technical problems, I may have just found where they are at.
