I'd get it repaired.
Seriously, if I've already bought a X360, I should feel that it was better in the first place, right? Well, the Ps3 hasn't really been catching up in library, and it costs around twice the price I paid for the X360 in the first place.
If it is out of warranty, I have an issue, and I'll need to think through some more. Still, as I already own a dvd player (amazing, huh?), my initial thought is that the Ps3 has far less value for me than an X360 would have.
Other than that, I might run off the two main options, and keep playing on my PC, while trying to get some cable to make it show up on the TV.
