Lending the "copy of Your Copy" is arguably not always personal use. The law explicitly only authorizes copies of your copy if those copies are "at rest" for "archival" purposes. I only ignore the distinction that this rule is only for computer software because I view digital video/audio data files as computer software itself. It's just a standardized format that tells an application what to draw and present on the screen and/or what sounds to make.

If you're not going to abuse the mechanic and only lend out fewer copies of your copies than you can count on one hand...then sure, knock yourself out. I don't think the law is ever going to be robustly enforced enough to seek you out specifically for doing this. Personally though; I don't think doing this passes muster under the expected fair and personal use unless you're loaning said copy to someone you live with.
