Perhaps with, NuppelVideo (container) using RTJPEG (CODEC)... Anytime
you have a MPEG Systems Stream (container) or use any MPEG CODEC in any
container, you're using the colloquial MPEG format.
Oh, and then there's MP3 audio, i.e. MPEG-1 Part 3 Audio Layer 3, or MP1
or MP2 (Audio Layers 1 and 2, respectively). Might be close enough even
if using NUV/RTJPEG with MPEG audio. I don't know whether AAC (Advanced
Audio Coding), which is specified as Part 7 of the MPEG-2 standard and
Part 3 of the MPEG-4 standard, would be considered "MPEG" (but, if
decided by a jury, I wouldn't be surprised if it were).
A rose by any other name is stilled owned by TiVo, Inc. ;)
