Does anyone know if there is an update for the Samsung PRL-3100? That's a unit that looks like the SIR-T150 but comes bundled with bigscreen plasma displays and has extra features like A/V switching and an audio amplifier. Mine is ver. 1.0 and it tends to freeze sometimes and won't respond to the remote. I'm pretty sure the SIR-T150 updates won't work because of the extra features and it used a different kind of microprocessor.
