I know that post could be a bit confusing, Mag. The very first discs I burned included about 20 tracks, with using many different rates from 128 to 320, including some VBR, all on the same disc. Some of the discs that I couldn't get to work were not burned by me. I guess I should have said "attempts" (plural), not "attempt" (singular). At any rate, no, they aren't converted back and forth but rather ripped using MMJ.
The posts you're referring to are fairly old; I've pretty much got it figured out by now.
As far as converting music already on the HD as wave files, I've got a utility that does that nicely. After to convert them you just erase the wave file & leave the MP3.
As far as setting up my folks PC for MP3 playback, I'll rip a bunch of there stuff for them next time I'm up there. There's also some stuff I'll rip at my place and burn to a CD-R, which I can just pop in their CD-ROM drive and add to their music library.
By now I've basically abandoned the straight 320 kbps rate and gone to all VBR at the highest settings. As a few guys here advised me, the VBR discs sometimes won't play back on all machines, hence the probs I was having. But the VBR tracks I've ripped w/MMJ all work fine in both the Pioneer DVD decks in the house (added a new one since then

), and all the computers I've tried 'em in play em back just fine. At any rate, notwithstanding the good results Witchdoctor gets with his DFX-equipted Uber PC, I find that 320 isn't entirely transparent with all stuff. Most rock sounds great, but some seems to trip it up a little. Piano and cello recordings can sound like nails on a chalkboard at 320 kbps, so now I just go with the highest rate VBR. I can attest that those recordings sound very good played back thru my DVD deck.
Thanks for the post, Mag.
