My RS15 developed the pink stripe issue just in time for the warranty (22 months, 1100 hours). Thanks to the posts on this board I knew to act quickly. It took four weeks. My projector is the only TV in the house, so I spent four weeks watching stuff on my 14 inch laptop.

I took notes on the process in case it would help others. One key observation is to call JVC often. They have more information than what is posted on the web and sometimes the process is blocked waiting for input from you.
Four weeks is far from the 72 hour repair time that JVC promises for these projectors. JVC really needs to improve this. With that said, I was happy with the overall experience. When calling JVC (and pressing 7), I always got someone within a couple minutes. The people I talked to were professional and helpful, which was good considering how often I called!
--- Week 1 ---
Fri 9.30.11 -- Shipped via FedEx.
Tue 10.04.11 -- Delivered and signed by JVC
Wed 10.06 11 -- Still not in system. Called JVC. They said to wait a few more days.
--- Week 2 ---
Fri 10.07.11 -- Still not in system. Called JVC. They said to wait until Mon.
Mon 10.10.11 -- Status: RECEIVED.
Wed 10.12.11 -- Status still RECEIVED. Called JVC. They said it has been assigned to an engineer but work hasn't started. I mentioned my concern about the OB being the problem. He looked and saw there were 4 in stock.
--- Week 3 ---
Fri 10.14.11 -- Status: WAITING EST PRT with an estimated total of $265.30. Called JVC. They said the $265 was for a new lamp (wholesale price). I had 1100 hours on the old lamp and was fine to get a new one at that price. They also said the issue was the OB, and they were waiting for the part to be shipped from the warehouse. He looked a saw there were 2 still in stock and said that once it came in it would likely be repaired very quickly.
Wed 10.18.11 -- Status still WAITING EST PRT / $265.30. Called JVC. They said the OB has been replaced and they were waiting to see if I wanted bulb replaced. I wasn't contacted about this. They took my phone # and said they would get someone from the factory to call me back. The web page updated with a place to enter my credit card info. They called me back as promised. I had them change my shipping address (to my work) and also had them make a note to ship me back my old bulb (they should last to 2000 hrs or more and mine had just 1100 hrs). Status changed: WAITING ON PARTS.
Thu 10.19.11 -- Status: ACCEPTED. The web page says its been assigned to a technician.
--- Week 4 ---
Fri 10.20.11 -- Status still: ACCPETED. Called JVC. They said the lamp was in stock it would be likely be replaced that day.
Mon 10.24.11 -- Status: WAITING PARTS! Called JVC. They said that after replacing the lamp they noticed a problem with the switch holder. They said this part would come in today and would be replaced right away.
Tue 10.25.11 -- Status: DISPATCHED. The website has a tracking number. It actually shipped out Monday evening. Expected delivery is Wednesday.
Wed 10.26.11 -- UPS delivery failed. The address was wrong. I called JVC and they had the correct address on file. It seems that the address was written incorrectly (by JVC or UPS) on the shipping form. UPS said the package was still on the truck, so I have to wait another day to get it.

Thu 10.27.11 -- I picked up my projector at UPS. I hooked everything up and it is like new! No more pink stripe and 0 hours on the bulb. This picture is amazing, just like before.

Let's just hope that the new optical block doesn't have this same problem or else I will be looking for a new projector in two years.
