Sharp Aquos BDHP20U issues

[taipan70]

I got this thing from amazon in early 2008 and it was refurbished. There hasn't been a firmware update for it since last October. It's played every movie since that update except for Crank 2 which just came out. I use it quite a bit and have to reset it every few weeks. Now I rent from netflix all the time and with Crank 2 I sent for a replacement disc and it didn't read the movie at all on either one. When I rented Taken it played fine, perfectly the first time and then I left the disc in and the player alone for a week and then on watching it again it stopped 80 percent of the way through. Now I just called Sharp to see about having it serviced and they said I could or I could wait for another firmware update. I was told there would be one but they couldn't say when. Does anyone have a suggestion? I was going to replace it for Christmas. Do you think I should tell netflix not to send blu-rays until then?
