If you really want to get some bang for your OTA buck, about $35 at Amazon gets you one of these.
Mediasonic HW-150PVR HomeWorx ATSC Digital TV Converter Box with Media Player and Recording PVR Function/HDMI Out

I've ordered one for every large screen TV in the house. It receives free OTA HD TV broadcasts via a *good* HDTV antenna and allows you to store them to any sort of USB drive (I've tried thumb drives, 500GB WD and 2 TB Seagate external devices so far). The recordings are in HD as MKS files and I can take the thumb drive out of the mediasonic unit, plug it into my Sony BluRay's USB front port and play whatever I just recorded in very nice looking 1080 resolution. I wish that the unit took the file names it recorded from the EPG like the Panasonic DVR did (before the digital conversion - afterwards nada). It instead records the channel name and number along with the time and date, which is enough to distinguish recorders.
In terms of bang for the buck and the number of problems solved for so little, I think this may be the "Most Useful Purchase" of the year. I've tried recording HD-TV to PCs and while it can be done, it's nowhere near as convenient or cheap as using a PVR. The recordings are stunning - particular compared to my old Panasonic and Polaroid DVRs which had a HQ mode but nowhere near as sharp as the Mediasonic's HD recordings.
It's got an HDMI, component and composite outputsIt's got an EPG and timed recording, too. Some people report issues with that which oddly seem to be caused by local TV stations setting their time signal incorrectly, which the Mediasonic depends on for timer recordings. Haven't found a way to tell it to stop recording after an hour, but it might be possible - it's just not obvious (on the Panny you just hit record again to add another 30 minutes of recording time.
Now, when there's four different things on at the same time that I want to record (it's happened!) I can just set each box to a different OTA channel and have at it. Allegedly there's a FW upgrade that lets the unit decode QAM, but I think I've decided that with Netflix, Amazon Prime and OTA in the DC area, who the fu& needs Comcast CATV? I only subscribe to the basic package which means local channels (fewer than the new box gets!!!), CSpan, WGN and the local public access channels.
While there are clearly "settling in" issues with the firmware and the hardware, I don't think I've ever seen an HDTV recorder for OTA broadcasts for anywhere remotely as cheap as $40 and I've made enough manual one hour records to different kinds of media that even if that's all it ever does and the timer recordings never work, it's still worth the money. Plays all the files from my other DVRs, too.
I'll post updates as I discover new features (or bugs) but so far, what a great Easter gift to myself! My wife is not as impressed, I'm afraid, because she's finally figured out how to use the current setup and fears that will be changed.
