Actually they are not different rips. They are the same rip. jEplode retags the MP3 upon download, and that's one of the main reasons why I had to use jemplode. I already have almost all fids on my hdd, but I was not sure they had the right tagging inside, so that even using some renaming sw would not be an ideal choice.
In addition to that, I used iTunes to change some of the tagging. The mp3s are, however, the same rip.
"Taym's Grab & Encode" is the comment I use in my empeg to classify the mp3s I grabbed and encode. I use to add that comment once they are in the empeg, so it is not in the FID/mp3's id tag but in empeg db. Once I download the file from the empeg to the hdd, jEmplode updates the ID3 tag including my comment.
