In the SCi-Fi Channel preview for "Cure" (episode 6.12) Peter Stebbings' character, Malek, speaks with a normal voice. In the final episode Malek speaks with the modulated voice common to the Tok'ra and Goa'uld.
Various episodes have been edited for syndication, removing occasional nudity and swear words that were allowed in the first-run Showtime viewings.
The syndicated version of the episode "Within The Serpent's Grasp" does not include O'Neill's quip about whether the Gou'ald long range visual communications device can pick up Showtime.
On the DVD version of the show, the beginning and ending episodes of season seven have had their formats tweaked. As originally aired, FALLEN and HOMECOMING aired as one two-hour episode with one set of opening and closing credits and the only episode titles are seen listed with the respective writers after the opening title sequence. The DVD devides them into the syndicated version of two separate episodes each with their own credits and with the separate episode title on each episode. The reverse is true for LOST CITY. Originally aired as two separate episodes, the two episodes have been merged into one with one two-hour episode with one opening and closing credits sequence and instead of being LOST CITY PART 1 and LOST CITY PART 2, the title is simply LOST CITY.
