When our son was a toddler, we stuck with dvds. I didn't really like anything on network. We had three Mister Rogers dvds (the one on friendship and love is wonderful and our son LOVED it, repeatedly); a Hap Palmer Babysongs (it just shows songs and babies-- used it for when I was taking a shower); a Preschool Power dvd (they are a Montessori based series which also features kids doing ordinary things-- fascinating to little kids) and some music performance/concert videos from a few pretty 'tame' artists (Bela Fleck; Crowded House; David Byrne...)....
At that age, my son didn't like Sesame Street or 'story' type shows, he really liked seeing older kids (real ones, not cartoon) and music. However, we avoided shows which featured relational aggression, such as Arthur-- too early to make sense of it.
I want to add, if your husband is using this as a sort of babysitter (and that's okay, so long as it's not for huge chunks of time-- we all need a break) -- make sure that the room she's left in is completely babyproofed. I had a gate between the living room and hallway and a kitchen swinging door we could wedge shut. Because I knew the living room was very, very safe, I felt comfortable leaving him so I could take a shower.
