Just got this.

Very small, three significant parts.

Tuner: Samsung DTVS22DPH261D

CPU: RMC RTD2885S / 87H30S1 (aluminum heatsink silicone-applied) [replaced with CPU thermal paste]

Memory: NANYA NT5DS16M16CS-5T 256 MBs DDR

Headers:
20 unsoldered pins by memory (possibly to/from storage media system)
9 pins unsoldered, 3 used by IR (HID input system)
4 pin connector JI01, leads to CPU (firmware programming)

More info later as I actually test it.

This unit also has VCR Timers for setting up recording times for a VCR. I think this is now the 3rd unit on the market with this feature.

Codebox CPUs - great for kiosks, terrible for DTV

I plugged it in. The first thing i heard was the heat sink cream bubbling around the CPU. What the hell? The unit still works - and the unit began to get warm quickly. I tried searching online about the CPU, nothing came up. It's new on the market.

Setup was pretty quick and easy. At one point, it tried to recieve a too-faint signal from Santa Barbara before picking up all of the other channels. It picked up all the correct names for each of the channels. The picture came on, I thought the connector was a bit loose, the picture was kinda fuzzy. I tuned to a cartoon on qubo, and the fuzziness was more apparent. Picture quality was 2/3 of what it should be. Aliasing and feathering pixels, ugh! I had to shut it off, couldn't look at it anymore! It was also slow to switch channels. I mulled as to think of a reason, then it hit me - they did not use a dedicated MPEG chip anywhere - the CPU chip is a "codebox" chip - it's like a place where a programmer can dump machine language into it and it runs the code. They chose to use this rather than to have a "catalog CPU," "catalog firmware" and MPEG decoder chips.

The RMC chip has the MPEG decoder software, uninteresting GUI (three 4-color icons,) closed caption mechanism and the program guide reader. One chip instead of three - better for the environment, hmm? Yes, but, the picture looks so crappy. It ran hot, unlike the combined heat output from other converters. One-man bands sure are lousy, huh?

The remote control is real huge compared to the others, which can be good for seniors. The directional keys are big, but it doesn't give much of an incentive to get this one over other devices.

The aspect ratio setting is the same for all of the channels - there is no individual channel settings. Program guide is minimal - only shows a few shows. No linking to any timers on this model - perhaps the other one has a different firmware.

Closed captioning is handled quite well. If you decided to use the Sunkey's closed caption system, the data would not be sent to your TV so you won't have double captions appearing. I don't know if it interprets captioning effects such as colors and flashing text - can't get MTV on this.

The main fail of this was that they didn't use a set of cool-headed dedicated processors to handle the task, they used a very warm single-CPU system that did not render the picture properly.

It comes with video cables and RF cable. I got this on eBay - this was most likely originally ordered from Meritline to get their cool-looking HDTV skillet pan antenna, as it comes free when you get this converter there. Considering the PQ, they sure do make up for its cost. Sure, it may look cool, but it won't perform well if there are airplanes or freeways in the directional path to the DTV transmitters.

It may be fine with low vision watchers or for small portable TVs under 15 inches, but for the rest of of us, I say: PASS ON THIS ONE.

awesome review Div!

So the single-CPU never rendered the picture properly in the first place or was this after the processor heated up (after a few minutes of use).

It was also slow to switch channels.
I have this same problem on my high end Mitsubishi LCD (w/ digital tuner). Such a dissapointment to flip a channel and wait up to two to three seconds for anything to display on the TV.

Hi,
I need to get a convertor for my 90 yr old mother. I like the idea of a large remote control and ability to turn TV on/off. Have you run across any converters with at least these two features?

>>The remote control is real huge compared to the others, which can be good for >>seniors. The directional keys are big...

Cheers.

(deleted irrelevant info.)

Checked the program guide. Shows 7 lines of details for one channel. Quite similar to the Airlink system.

Remote does not have a TV key. Try the RCA DTA800 brand.
