Dual layer discs, with each version presumably taking up one layer. All had a trailer and a few light extras. All three came in the cardboard snapper cases.
I re-watched mine synced up to the Criterion commentaries recently. FRWL and Goldfinger held up pretty well on a modern tv. Dr. No had a noticeable bit of compression artifacts on ocean waves though.
TSWLM and Moonraker also came out in similar THX editions, but in regular DVD cases. Moonraker was the only genuine case of DVD rot I've ever had, so I was relieved the Connery discs still play.
