[mythtv-users] Can't convert TV recording MPG files for other computers - codecs

Myth recorded my shows from satellite (DVB) and from analog cable via
PVR-500.  Myth creates these files in the /storage/recordings directory

I'm using Windows based tools to view/play/convert because I've pulled my
hair out with mencoder.

I'm trying to resize these recordings to 800x480, 600kbps VBR video, 192k
audio, deinterlave, denoise (if avail), crop letterbox bars, etc.

The output should be mp4 (MPEG4-ASF/2) format to play on Windows Media
Player mobile.

If your suggestion is to use mencoder, can you point to a non-codec expert
site?  (Some sites assume a huge amount of codec/video knowledge)

When you say "The mpg files that Myth creates", how is Myth creating them?

Are you talking about .mpg files created by a PVR-x50 card? Files transcoded

to mpg by Myth? MPEG streams captured by an ATSC or QAM capture device?
captured by a DVB device of some sort? h264 files from the BBC or the like?

And what do you mean by "other computers - codecs". Are you wanting to play 
the files on a Windows machine? Windows by itself does not have the mpeg2 
codec, you have to get it somewhere, often as part of a DVD player program.
don't think the h264 codec is included with a standard Windows install 
either, you would have to get it from someplace.

So if you could be more specific as to what these files are, and what you
to do with them, folks here can probably give you better help.

What conversion programs fail? ffmpeg or mencoder should be able to
just about anything Myth creates. Remember that with ATSC, QAM or DVB Myth 
does not "create" the file, it just demodulates and records an already 
created stream.
