He was very helpful, it's not often you actually talk to someone outside of engineering that knows what they're talking about, but he was sharp.
That was nice of AVer to get back to you right away, and with a knowledgeable person/info. Just try that with your cable service provider! (there's an excercise in futility).
2 coax ports - 1 for ATSC, the other for NTSC.
looks like the lower is for analog
It uses the exact same 5th gen LG ATSC demodulator chipset that the Dvico RT 5 Gold uses
and many other devices too!
Aver uses a NEC mpeg encoder/decoder chip instead of the Conexants on the Dvico cards.
As a note, the Conexant IC on the DVICO cards is an A/V decoder (analog to digital conversion) and bride interface. The NEC is a video decoder (analog to digital conversion) and a MPEG2 A/V encoder. It could also act as a bridge interface if the card operated on PCI, but it doesn't given that its a PCIe design instead ... the bridge duty is handled by the Micronas IC instead.
A common mistake people make is to assume that the decoders mentioned above are related to the mpeg2 decoding playback, but that is not the case. In both cases, the mpeg2 decoding is down off the card, downstream, by the host CPU, via the algorithims of a software decoder.
The only (potential) downside of this NEC chip from a features standpoint is it doesn't support DD.
This would be for encoding analog audio sources. And alas, DD is not supported, although the chip's "big brother" (uPD61154) does. But no luck here.
half-height bracket, 1.5mm male audio to L/R 2 port RCA female adapter, hard composite to S-video adapter, a wire adapter (not sure what it's for) and the warranty info. The lack of a CD with drivers was kinda odd, although most people know to go to the manufacturer's website to get the latest ones.
nice about the half height bracket. strange about the CD. the cable is likely an internal audio cable.
For ATSC OTA, the M780's image is a little cleaner than the RT 5 Lite...The images of the 650 and 1600 were both very good ... I only did head to head comparisons of image quality between the RT5 and the M780.
The cards have nothing to do with the image quality of a DTV source. Your comparison is only valid for the software decoders you used with each card.
and it's signal lock is outstanding. It gives me 100% strength on all channels, whereas the RT 5, 1600 and 650 all dropped to 98% or 95% on one or more channels.
you can't compare signal strength readings between cards -- there is no universal measure. So what one card's software reports may have absolutely no comparison to what another card's software reports.
The 650 is overpriced, IMO - it rides the PCI bus, no QAM and it's not a real dual tuner.
As for QAM, ATI just doesn't support it in software (but the hardware is capable); as for dual tuner, true, its only a hybrid receiver...many people seem to have thought the ATI was a dual receiver (did ATI ever advertise this as such?, cause I don't know where that notion comes from). As for PCI -- I'm not sure why they haven't released a PCIe version (I guess they figure that their bread and butter is still earned by the PCI)
I'd add that the Divco model that you were previously waiting on is completely mis-priced...they've priced themselves right out of the market. I'd expect a big drop there soon.
The 1600 is a pretty good value, especially with the rebate that just ended, but I've never been a big fan of Hauppauge's driver support, not to mention it's another card sharing your PCI bus.
absolutely agree about Hauppauge and drivers.
Here's some pics of the card and it's chips. Sorry about the image quality, had to use my video camera, couldn't find the still.....
Shots were fine. 4 IC's of interest that you left off were the two small ones under the RF modules. These are likely audio ADC's for the Audio input. The one lager IC beside the lower RF module, which looks like a Philips analog TV demodulator. And the one chip just to the lower right of the Mirconas nGene IC. I believe that is an eeprom for the firmware for the APB 7202A.

LG. Dvico is the card vendor, LG is the IC manufacturer.
