500MB is the minimum memory specified here:

from which I conclude that BIAB 2012 has been tested on such a system - I've got 1GB, so memory isn't an issue.

My problem isn't that things are slow, it's that they don't actually work!

Having said that, I've found that I can place a .MGU file in ..\BB2Go, get BIAB to render it to .MP4, then download the .MGU/.MP4 pair to my iPad and have the iPad play the properly rendered song - so the mechanisms are all in place, they just don't seem to work through the Windows=>BB2Go dialog box.

(It seems that .M4A and .MP4 files are interchangeable for this purpose).

Can anyone confirm that he/she can get this sequence to work:

1. Create a BIAB .MGU file with RealTracks (call it MyTune.MGU).
2. Generate the music, complete with RealTracks.
3. Copy MyTune.MGU to the ...\BB2Go directory.
4. Use Windows=>BB2Go to Generate a .MP4 file for MyTune.MGU.
5. Download MyTune.MGU and its companion .MP4 file to an iPad using the Band-in-a-Box Service.
6. Play MyTune on the iPad.

If you can do this, then there's clearly something not right about my set-up - I'd rather know this is the case before embarking on HD replacement, memory upgrade and OS reinstallation!
