In a way, your question prefaces are unrelated. An hour's worth of DV tape is 13GB if it's NTSC, slightly less if it's PAL.
DVDs hold MPEG if it's playable, or they can archive raw avi files up to nearly 8 gig if it's a dual layer DVD.
If it's MPEG, it's compressed more than DV is. DV is already compressed 5:1. MPEG at low bitrate is not an editing format. It's a delivery format, and attempting to edit the MPEG will degrade the quality, usually substantially enough that it can't be broadcast. If it's cuts-only editing, they can edit using a tool like Womble and simply split out segments and rejoin them with no recompression. Ulead Media Studio Pro can do this reasonably well too. In fact, it's the one and only reason I still have the Ulead MSP on my computer is for MPEG editing.
