The PS3 itself will not record or allow you to watch TV shows best i know. If though you have Mythtv running on a Linux distribution that has REPLACED the PS3 OS then yes. But i would not suggest you do this unless you are VERY familiar with Linux (I am not going that route though i have used Linux for many years). What i run is a Mythdora Linux distribution that will "see" this item as a video device. On the Mythdora box i will then "share" the media files that are recorded via "MediaTomb" to the PS3. Still not easy. Post back if you find some thing different.
