I was able to give some of these events in 2003 (and will be giving more in 2004). In December, I gave a talk on patch management and SUS. You can get a recording of this session athttp://www.placeware.com/cc/emea/view?id=msft0912cs&pw=RMG9GT. This uses PlaceWare, so to see the full webcast, you will need to load some software (you will get prompted for it).
The overall UK technet site is http://www.microsoft.com/uk/technet/learning/ - enjoy!
