All, I purchased one of these units to install at my church. I did a basic review over at Amazon, and posted some pics. videobruce commented on that review and has requested a more extensive review, but to be frank, I don't have a ton of free time, the unit is not at my house so it requires a trip up to the church building to mess with it, and it is only ~$45. Spending too much time documenting every aspect of this box just doesn't make much sense.
I am happy to help answer specific questions, so If you want me to check for something on the unit for you, let me know and the next time I am working up there, I will try to get the information you request.
FWIW, I purchased the box because I needed an inexpensive HD ASTC tuner to feed a video switcher, and this one seemed to be as inexpensive as they got. The PVR function was just a bonus to me, and we won't utilize that functionality much. It is currently hooked up to a projector for March Madness in a youth area via the composite video output, so keep that in mind when asking me to check things on it. I have verified that component and HDMI work as expected.
