Excellent. Breaking it into two tables makes it a lot easier to read. Each one fits, even on a smaller (1440x900) monitor.

I've been making changes to the tables since posting them on Jan 31.

See latest changes here.

Free, abundant OTA television separates this country from many others. ATSC1 has only been in force since 2009. The wireless industry has enough spectrum. Enough of 'planned obsolesce'.

Which off air DVRs have the strongest tuners

Looking for a new DVR, I have a IVew and a TVio series 3 DRR which is HD. But the picture is poor quality for HD and some dark on the TVio. Both of these have weak tuners as my signal is not the strongest. Both do drop out on signal, My Question is which newer DVRs have the Strongest tuner. Both of my Vizio Tvs have much stronger tuners never loose picture, as I am off air user not cable. If I buy to try and see if it has strong tuner then I would need a Store with a very good return policy.

There shouldn't be a whole lot of difference between tuners these days. It sounds as you are need in a serious upgrade to your antenna. What exactly do you have?

Features common to all boxes: All these boxes have HDMI, composite video, and L/R analog audio outputs, so I removed those rows from the table. All boxes can output the same five resolutions via HDMI and/or component: 480i, 480p, 720p, 1080i, and 1080p. The composite output is always 480i, naturally.

New Models: HomeWorX has a new HW-130 model which is similar to the HW-180, but smaller with an external power supply. ViewTV now has a new AT263 model. It looks a little smaller but seems to have exactly the same features as their older AT163, so I didn't create a separate column for it. Finally, Channel Master is now selling one of these too.

I think the RCA DTA880 clone may no longer be on the market. I couldn't even find a decent picture of it on the Internet, which is why it has so many question marks. Edit: Found a listing at eBay that shows pictures of the DTA880 box. That's good enough, because the box has a drawing of the back panel. I've filled in its video and audio outputs according to that drawing.

I tried to identify the SoC used where I could, mostly because different SoCs require different, incompatible firmware, so it's important if you're trying to ensure compatibility of your recordings when replacing one of these boxes, or if you experiment with "foreign" firmware. All these boxes seem to use either a 7816 or a 7802 SoC. The iView 3500STBII and HomeWorX HW-150PVR have been sold with each of those two SoCs at various times.

All the firmware for the 7802 SoC I've seen addresses a longstanding bug with displaying closed captions on playback. Unfortunately the 7802-based iViews have managed to introduce a few new bugs in the process

Thank you for the summary! I had an iView that died after a couple of years and then a Homeworx that just appears to have died after a couple of years....but have liked the functionality.

I think I'll try the RCA next based on your table: even if it's basically the same internal system, I'm hoping the External power supply gives me a little longer life. Thanks!

Hope so. The nice thing about an external power supply is if that fails, you can replace it without replacing the whole box.

I had an eBay link for a seller with a couple of RCA DTA880s, but it looks like they've sold out now

If you can't find an RCA, the iView 3200 also uses external power. The firmware is buggy, but if you still have the remote from your HomeWorX, you can cross-flash the 3200 with certain versions of Homeworx firmware to eliminate the bugs. Check the latest posts in the iView 3500STB thread for more details.

The DTA880 is available off the shelf at many Walmarts: http://www.walmart.com/ip/RCA-Digita...rding/46583029

I never noticed they use a wallwart.

Walmart wallwart... I'm now going to be saying that all day for no good reason.

Edit: These are still at two of my local Walmarts. Checked this week.

Yet another iView clone has hit the market. This one bears the Channel Master brand: http://www.channelmaster.com/Digital...m?Click=103354

It's a 7802-based box that looks like an iView 3500 or HomeWorX HW-150. The most obvious difference is the external power supply. It's brand-new so I don't know how buggy the firmware is.

Now I have to update my table again

^^ no real mention of recording(it mentions the USB port is for using it as a "media player") but I can't believe it wouldn't have that function.....of course I wonder if it has the pause live TV function

Where does the assumption of recording capability come from?
The website indicates it is a replacement for their previous CM-7000/7001 converter boxes which were basically CECB's. I know the CM-7000 didn't have recording capability (I have one) and I'm pretty sure the 7001 didn't either. So why is it presumed this is an iView clone?

If you download the user guide, it does explain how to record - and how to set the time-shift buffer size. So presumably it has both functions, but it is odd the main Web page makes no mention of either.

Maybe they didn't want to compete with their own DVR+. Of course the MStar boxes are toys compared to a DVR+, but a lot of unsophisticated folks might see an under-$50 DVR and wonder why they should pay $250 for a DVR+.

OK, that all makes sense from a marketing perspective. I would presume that Channel Master is simply buying the box from a third party and reselling it the way they do their DVR's. So it probably works like all the other iView clones -- the good and the bad. If used strictly as a digital tuner to feed an old analog device or an analog capture device, they work quite well.

I note this unit has an HDMI output. In your table of iView clones you don't have a row for HDMI output. Is HDMI output common across the clones.

Yes, every MStar box I've seen has had HDMI, composite video, and L/R audio outputs. I used to have rows for them in my table, but every column had a green X so they seemed redundant.

All MStar boxes support the basic five resolutions (480i, 480p, 720p, 1080i, and 1080p) via the HDMI (and if the box has it, component) outputs. Of course the composite video output is always 480i.

I don't know anyone who's bought the Channel Master-branded box yet (at the moment, it's a bit pricier than the other clones), but from everything I've read, it looks very similar to the HW150. Only differences I've seen are, the CM-7003 has an external power supply and a hardware channel 3/4 switch.

They support 1080p over component? That's unusual for a box sold in the US; component is usually restricted to 1080i as a futile anti-copying measure.

Well, they seem to, at least. When I switch from 1080i to 1080p using component cables, the screen has to resynchronize with the signal. And my HomeWorX says it's set to 1080p at 60 Hz. But since I'm watching OTA content, it's just upscaled from 480i, 720p, or 1080i anyway.

My guess is that since all these boxes can play is unencrypted, un-DRM-encumbered content, nobody really cares about trying to make it hard to record their output. So they can get away with things that would set off alarm bells if we were talking about a CableCARD device or Blu-Ray player.
