FFPs and MD5s: These insure that the files you DLed are "authentic". If the MD5 you have matches that of the original, you know you have perfect copies of the original. Also, with you are able to verify if your files have any errors.
ETREE naming standard: This has slowly become obsolete. I started a small discussion on the ETREE Forums about modifying the naming standard to combine the iPod standard of "01-song name, 02-song name" and the ETREE standard "bandnameYEAR-MO-DAd1t01, etc".
But after further thought, I decided that the old ETREE standard is perhaps still pertinent. If I DL a show that only has song names, and not track numbers, in the file-names, I am unable to figure the proper burning order. ETREE naming standard insures I know how to burn the tracks properly.
Also, when I copy over all my FLACs onto my HDD, they all line up in alphabetical and chronological order. This is really nice...
As for SBEs, you should make the attempt to correct these before you seed. If you do not, DLer #1 will "Fix" the SBEs one way, while DLer #2 will "Fix" the SBEs another way. You now have 2x different filesets - although they are from the same exact source, they may produce differing FFP/MD5s.
I tend to fix every fileset I DL so they match the shows that already exist in my archive. I keep track of the original FFP/MD5 - I copy them into the text file...
