2005 Prius A/C Problems

Hello fellow Prius owners & mechanics. I previously wrote a post re: A/C problems and want to post a follow-up with video. Here is a recap on the problem. I had just warm air blowing back in May of 2012 and had the Toyota dealership do an A/C recharge with dye to find the possible leak. 14 months later I have warm air blowing and the service dept. tells me they found an extremely slow leak at the evaporator and that the repair cost would be $1100.00. Since I did not have the $1100.00 they told me that they would recharge it again for $170.00 and I should be fine since the leak held for 14 months this last time. Being in Florida where A/C is required I opted to go with this plan. The recharge lasted 5 days and I'm already blowing warm air. The service dept. advisor assured me it was an extremely slow leak and the recharge will work for a while. I really want to trust these guys but have a tough time trusting any service department of a dealership. I have a strong feeling that they did not do the recharge right or gave a me a cheap band-aid fix to now put the added pressure on me to go back and have them replace the evaporator and make the big bucks. Here is my big question though. Before the problem with the A/C I never remember having anything show up or be seen moving in my glass sight viewfinder on my A/C lines next to the "H" cap. Now, when I start the car and put the AC on I get a fluid movement in the glass sight viewfinder. I included a video. Since I see fluid here and what looks like a fluid flow or bubbles in this viewfinder yet do not have cold air is this a problem with the way the technician recharged the A/C unit?
I can use any of your advise and expertise. Here is the video of the sight finder as it looks right now.
