> Video converting fury (general and C905)

I have come to a point where I really need to get the facts straight about video containers and codecs. I really really liked M3 for converting movies to watch on my K800 (yes, I can enjoy a feature film on its bright, sharp 2" screen). Importing these movies to my C905 though, I can't get them to play. Instead I have taken to using Super, producing mp4:s with video mpeg4 and audio AAC. The outcome I find inferior to that of M3. Low light scenes are plagued with bad smearing and compression effects.
My first questions deal with containers and codecs. I understand mp4 being one 'container', 3gp another. Is mp4 always superior to 3gp? And what about video codecs? Xvid/Divx are codecs, right? What's the difference? Will SE feature phones play anything encoded with some of these? Or is mpeg4 my best choice here?
My second question is: why will my K800 play files my C905 won't? Using M3, I have always chosen "video codec XviD MPEG4 simple". Meaning what? Is the codec XviD or mpeg4? The audio codec is LC-AAC. The difference from just AAC? Which setting is it the C905 does not like? I use a bitrate of 336 kbps and a framerate of 25 fps.
Well...sigh.

Really? Will it crop 16:9 to 4:3 if desired?

Will I need to purchase or is the free version enough for converting movies? List of features states free version is limited to 30 secs of "video encoding".

Simply put, XviD is just the open source variant of DivX (its not a coincidence DivX spelled backwards become XviD). Both are just names of codecs, not names of video formats. The name of the video format both uses is MPEG-4. To some extent, both codecs are exchangable with each other i.e. most videos encoded with XviD can be played in a DivX player and vice versa (compatibility issues may arise if "special" codec settings have been used to encode a video).
Video formats are usually not restricted to any particular container/file format. Container/file formats are on the other hand usually restricted to what video and audio formats they can carry. In generl, it's the video format and not the file/container format that decides the quality level. 3GP is just a simplified version of MP4 and can carry less video and audio formats.
That's all info I could gather on the internet for you. Hope it resolves some of your questions.

Thanks for your response. I will look further into this in the days to follow.

With Super, I use mp4, xvid codec, 336Kbps, 25 fps, 320x240, 11:9, high quality.
aac audio.
I seem to get acceptable results. Don't use the "Sony Ericsson 3gp" option if you are - 3gp is a low quality version of MP4 for mobile devices (old mobile devices - before they got powerful)
