Cheers for all your chasing, BeeP, I'll give it a go. It's the most promising lead so far. It was definitely a shareware that various firms latched on to.

The setup exe is in the Transcode/English subfolder

What ^he^ said - I unzipped the PMPT.exe and ran Transcoder/English/setup.exe

I tried attaching just that setup folder (3.8MB zipped), but it didn't attach.

I assume the Dropbox link will work, but if not I can fling it over email.

Poor Manthorp. The malicious pixies of frustratingly-close-but-not-close-enough have made the program work perfectly but fixed the output resolution at 224x176 whereas his player will only accept 96x64. The program was designed to offer a range, but it looks like it's been messed with and the option is greyed out. 

Ta BP. I appreciate it

Your efforts have been of the stoutest WmA.

I am in (hopeful, but currently one-sided) correspondence with Pixtree. There is always a way,
