thanks for the response-
below are specs…
looks like audio does have to be AC3… Seems like either Heuris or PixelTools compression software are 2 options, they’re just extremely expensive… and thought there might be a better way to get to MPEG without rendering, compositing, rendering, compressing.
thought there might be something in Final Cut Pro HD, but can’t find any info about HD MPEG possibility.

but my major issue: I can’t play the original file that’s currently playing on the system.
tried installing MPEG2 addon to quicktime, installing all Divx codecs, and on PC updating Windows Media, but nothing works.
Thought maybe the file was corrupt, but got an HD MPEG out of pixeltools demo export plugin, and I get the same error message with that also (not a file QT understands -2048).

Does HD MPEG assume MPEG 2 (It’s not for DVD purposes)? Can’t get an answer on that one.

Thanks again for your help-

MPEG specs are below:

* MPEG files must be encoded as a Transport Stream.
* Elementary Video stream must be Main Profile High Level MP@HL 4:2:0.
* Elementary Audio Stream must be AC3 encoded.
* Transport stream packet size is 188bytes. This is the standard size,
although some encoders generate
packets of 204 bytes. The extra data contains error detection
information, used for satellite transmission.
* Stream must start with an I frame and finish on a 188 bytes packet
boundary.
* The two most popular resolutions supported are 1920 x 1080 x 59.94
interlace and 1280 x 720 x 59.94
progressive.
* Recommended Video PID numbers are 17, 33 & 49. Audio PID numbers are
video PID + 3. Try to ensure
that all files are encoded with the same PID. MediaSonic normally use
49.
* The standard ATSC bit rate is 19.39Mb/s. Higher bit rates up to 50Mb/s
can be accommodated.25Mb/s is
an excellent compromise between image quality and file size (storage).
* It is preferable to use closed Group of Pictures (GOPs) if this option
is available with the encoder. The
preferred, though not required, GOP size is 15 frames. This provides a
good compromise between
compression and random access in the stream.
* A GOP pattern containing I, B & P frames will provide the most
efficient compression.
I B B P B B P… generally produces good results.
* Each GOP should contain a sequence header.
