SSTV pictures on HF are often in Scottie-1 mode, while the ARISSat-1 are in Robot-36.  Perhaps you are receiving in the wrong mode?  That's about the only thing I can think of that might be mis-matched, if HF works, since with the satellite's downlink being in FM mode, you can't be off in audio frequency.  I presume you're seeing the audio in the waveform display.

MMSSTV has an automatic mode detect which I have found to work very well.  I just click on that, and off it goes.  I think everything is default.  Have you tried that?

Good luck,
