Aww, you poor thing . Unfortunately I can't see your video, MySpace says it's private.

Have you tried rocking/jiggling your bub in your arms so that he is almost asleep and then putting him down? I used to do this with DS2, I'd wrap him and get him almost asleep in my arms and then put him down. Over time I put him down a little less sleepy at a time and eventually I could put him down with no fuss.

It will pass, I can't tell you when, it's different for every bub. It took DS1 6 months to go down for naps with no help and it took DS2 until 7 months.
