Honestly if this is going to turn into an expensive exercise I would consider getting a pre 25xx PS3 (very early slim or any fat) and throw CFW on it. It's very easy to do the latest OFW has an exploit.
That can be hooked up to any tv and for PSP stuff you can run iso dumps, PSP for PS3 PSN pkg after unlocking them or even convert some PSP iso to remaster type using some software on PC.
I don't think PS TV is an option because it only has hdmi?![]()
