Haven't heard this but it's probably true if they are developing a box that uses MPEG 4. Encoding is done by h.264 developed from Apple's Quicktime format. Here is some good info from Apple's site about H.264 that can scale from 3G phone content to HD. Bold emphasis mine but think about what this will do to reduce bandwidth!

In which industries does H.264 play a role?
H.264 is an extremely scalable codec. From 3G to HD and beyond, H.264 provides excellent quality to the broadest range of bandwidths and user scenarios. Best of all, H.264 is a standard — so companies across the telecommunications, consumer electronics and broadcast industries can create products that will interoperate with one another. H.264 has been broadly adopted by organizations representing everything from mobile phones to HDTV, and you will find a broad spectrum of interoperating products — consumer and professional, hardware and software — supporting this standard. Visit mpegif.org for news and product announcements about H.264.

How does H.264 compare with MPEG-2?
HD MPEG-2 content at 1920x1080 traditionally runs at 12-20 Mbps, while H.264 can deliver 1920x1080 content at 7-8 Mbps at the same or better quality. H.264 provides DVD quality at about half the data rate of MPEG-2. Because of this efficiency, H.264, an ISO standard, stands to be the likely successor to MPEG-2 in the professional media industry.
