hi, please execuse me if its not the right forum to post on.
I am completely lost, as the title says.
as a reference, I am familiar with all kinds of format Encoding/Editing/Converting.
I can't do a single step in any aspect of dealing with H264 in an mpg.
I encoded some footage with MainConcept's H.264 Encoder &main profile that has the following specs:

Code:
codec: MainConcept H.264 codec &main profile
container: mpg
multiplexing type : mpeg2
for playing the encoded mpg I had a hard time figuring out which player could play it,It played with only Media Player Classic after setting the following:
Code:
added to Options/Filters/Overrides the MainConcept H.264/AVC Decoder, set its merit to "Prefer" and added a new sub type "{E06D8026-DB46-11CF-B4D1-00805F6CBBEA}"=MEDIASUBTYPE_MPEG2_VIDEO to its MEDIATYPE_Video <-- very important otherwise it won't decode it in MPC.
I tried to render this mpg with GraphEdit's Render Media File option, but it only produced:
Code:
file.mpg(output pin)--->(input pin)Ligos MPEG Splitter(output Audio pin)---->(XForm In)MPEG AUdio Decoder(Xform Out)--->(Audio Input pin)Default DirectSound Device)
with no Video!, so I tried to make the graph myself, added and tried a few demultiplexers and splitters found in DirectShow Filters, but with no avail.I had three major results:
-demultiplexer won't connect input to the file.mpg
-demultiplexer connect its input to file.mpg but produces only Audio output
-demultiplexer connect its input to file.mpg and have both Audio and Video outputs but the Video output won't connect to MainConcept H.264/AVC Decoder input!and says there is no common mediatype between the two of them.

now, how can I force this pin connection, although if the mediatype is not common ?
or how to make a graph that can be rendered successfuly and afterwards could be imported with Avisynth for the purpose of editing the file.mpg
what really makes me scratch my head a lot is why they(MainConcept) decided on an mpg container ? because it complicates things a lot, instead of the standard mp4 container as mentioned in ISO 14496-14.

I am lost, please enlighten my way through.
My great thanks mainly to www.videohelp.com and www.doom9.org for the wealth of info that solved me a lot of problems.[/code]
