Play you play tv surfing by pressing b when it shows the picture in at the top tea time you play by pressing a and b press the button on the side with the long cup. and no you can't connect v5's with v4.5.
For the tea game it is a bit confusing because i couldn't figure it out in the beggining but what you do is when the tea is upright, (eighther left or right side) you click A for left side and B for right side but if they are both upright you click A and B. From level 0-4 it gives 0points from 5-9 it gives 10 points rom 10-14 it gives 50 points and from 15-19 it gives 70 and when you reach 20 (last level) you get 100 points. (The upright tea cup looks like this >

And the fallen over one like this > (this isen't very good cos i can't join the sides up so i will find some pics)(and ignore the dots i just needed them so that the cup could stay in place)
