Only for the channel numbers over 100. The ones in the 70s are still MPEG-2 (for now) for older receivers. HDNet and HDNet movies, which previously didn not have channels in the 100+ area now do (305 and 552 I think, something like that).
Even though the older channels have been mapped to both the 70s and the 500s for a while, the MPEG-4 feeds just started today, so you have not missed anything if you were watching the channels in the 70s. From now on, however, you should get a better picture and smaller file sizes if you watch or record the MPEG-4 feeds in the 500s, etc...
Now that we've thrown 'em off the trail, use the form below to get in touch with the people at Engadget. Please fill in all of the required fields because they're required.
do the mpeg4 channels just replace the mpeg2 channels if you have an mpeg4 box?

I did not know that. I've been watching my HDNET and such on those lower channels....would have been nice to know this.
