For those of you who responded, I believe I figured out what happened.
I had been tweaking the gap settings on typical rock albums such that I'd get one or two :02 second tracks of silence for each real track. I figured that once I imported them into iTunes, I could use the "join track" feature, as I couldn't tell by using MC10 which tracks were silence or soft fade-outs.
As a result, I'd be putting in around 25 tracks on a single CD.
It seems MC10 simply can't handle such a load.
I managed to import a a series of Bach cello suites, 9 tracks total, and Beethoven's 9th, 4 tracks total, without problem.
But importing the multiple silent tracks? It won't work.
I would have REALLY appreciated it it the help index would've explained this.
The warning messages I got above, "invalid parameter," "couldn't start audio recordin....", and whatever the third one was are not explained anywhere in the index.
It's not to much to ask of a sofware writer to make sure that warning messages in your program are explained in your help index.
At the moment, I'm experiencing the double headache of a .wav file similar to those that I managed to get onto my iPod last night unable to play in MC10 (it fast forwards itself with no audio), which made me try to drop it onto a CD-RW, which MC10 is refusing to believe has been erased (I got to the "successfully erased" box, hit OK, but upon trying to drop files into the burn box, I get ten minutes of whirring D: drive and finally a box that says Drive D: does not have a writable disc).
This has been the most exasperating week I've spent with my computer since Dell and my DSL provider decided to use me as their own private no man's land.
I appreciate your help JohnT & Glynor, but I can't wait to finish getting my final few LP's imported so that I never have to deal with MC again.
At almost every step of the way: a problem.
