Ok I got another thing for you to try.
Download Graphedit and the filter pack for graphedit. Graphedit should install no problem but you will need to modify the batch file that comes with the filter pack to include a path to the install files to the registry. If you can't figure that out get regdrop and use it to register the filters.
Graph edit is really cool it allows you to link different software packages together by just drawing a line between them. Hopefully Graphedit can find the software you already have to play back smvs and use it to convert to another format. It is a little complicated at first but kinda fun once you understand what is going on.
Once you install Graphedit and the filters (which may come together in one download) click on render media file. Find your smv file and try to render it. Render = Play. Hopefully Graphedit will be able to play the smv file. If not we are still stuck. If it does play smvs then we have some work to do. Private mail me if you get GE to play your smv and I will help you figure it out.
I use GraphEdit to convert dvd sound to mp3. In Graphedit you insert filters to do each job in a chain. The Filters to convert dvd sound to mp3 sound are: Source, splitter, decode, encode, cleanup and file writer.
The first filter is Source and all it does is pick the file you are using as an input in my case a text file containing a list of vob files that contain both video and audio info from the dvd, in your case the list would name your smv file/s.
The next filter is splitter which is used to seperate audio from video. In my case I'm only interested in audio. In your case it will be video or both.
Next is decode, this is where the work is actually getting done. In my case the audio is decoded. From this point it could be rendered (played back to listen to) or re-encoded to another format. I re-encode to mp3.
Next step in my case is to re-encode to mp3. This is done with an encoder filter setup for the proper bitrate and sample frequency you need in the output. In your case you will have an mpeg filter in this spot.
The next step I really don't understand. All I know is that you need to have a filter called Wave Dest between the encoder and final output. You may not need this step.
Last is the file writer. You will need to pick a path and file name. This step actually saves the conversion to your hd instead of dumping it into the big bit bucket in the sky.
Give me fuel, give me fire, give me that which I desire.
