I'm on v254; previously had v253 and the tuner worked perfectly. I'd say Hijack isn't your problem.

Do you have the low-battery icon when you start the player? If the voltage drops out too much, the tuner turns itself off. If it does this while the player is starting, then it doesn't get detected.
