I have the DVD too, (which my husband labelled "it's time to sleep you little bleep bleep!") and found it was useless for my first baby. Ended up being too traumatic for both of us (he ended up vomiting and pooing the minute I left the room, and I was never longer than 5 minutes). It just didnt suit him as a baby - he figured out his own schedule and slept through when he was older (and he still hates being left alone!). Didn't even bother for my second, the difference was he was a good sleeper from the start and still falls asleep whenever or where ever he likes and he's 16 months old.
A good one to settle baby, even if it doesn't put them to sleep is called "the sounds of silence" but I can't remember who produced it. It's a CD and book, the CD is the most bizarre sounds (mimicing the sounds of the womb, white noise, rain etc) and it's great for settling them when the are screaming their heads off - just make it louder than they are (truly!). I bought mine from Target, but if you google it, I am sure you could find a supplier.
