Digital cable tuner card confusion ??

[shadowknight]

I'm looking for a tv tuner card that can handle digital cable. I've been looking around and most of the ones that I've found say ATSC then say they are for "over-the-air" hdtv signals not digital cable. I looked at the ATSC website and from what I can tell it's a general standard not just "over the air". So, I'm wondering if these cards will work. I need some suggestions from anyone using digital cable and mythtv and recommend a good card and setup. TIA

may have found one. It will be a few weeks still before I get around to it but when I do I'll update my progress here.

Just to keep in mind:

As far as I know, there are only two cards that support CableCard, and neither have Linux drivers. I don't know where you're from, but if you're from the States, then you're going to be SOL for a while.

Yea, I've been doing some more searching. I think the box in the link above would work and but I'm still confused about QAM and still waiting to hear back from my cable provider so I may just shelve this for a while and wait for everything to become more standardized.

Your profile doesn't show where you're from, but if you're in the US the cable companies are legally required to carry the over-the-air networks in unencrypted QAM. In addition to those channels they may or may not provide other channels.

I have an HD Homerun unit hooked up to my myth system and for the most part it works like a champ. I get all the network channels and TNT-HD over it straight off the coax cable.

If you speak German: http://vdr-portal.de/board/index.php

I can compare Nexus CA/TT-2300C to Cinergy 1200. The Cinergy has no mpeg decoder chip for recordings. The tuner on the Cinergy is better than the tuner of the TT-2300C. This results in a better Quality and less errors. QAM 256 on Cinregy is fine. With TT-2300C there occur much more errors with QAM 256. Some persons in the vdr forum reported to be not capable of receiving QAM 256 with TT-2300C.
The driver of the the TT-2300C seems to become worse in the last kernel versions. When I was testing the cards there occur more errors. So if you don't have a good signal quality, you could get into trouble with the TT-2300C.

Thanks for the link but sorry I can't read german I'm in US. Let me clarify a bit here. My cable into the house is Digital, however only a few channels are actually HD. What I need to know is, are the normal channels (presume analog) able to be read by an analog card or do they need a digital card since the line itself is digital? I can't seem to find any info on the encoding of the normal channels on a digital line. Hope that clarifies a bit.

analog channels can be viewed with an analog tuner and the digital channels can be viewed with a digital tuner. TT-2300CA can read analog and digital. But you have to reload the modules before switching from analog to digital.

[shadowknight]

Thanks. I wasn't sure if the encoding was different since the line itself was digital.

I could've sworn that he would need something cablecard compliant in order to view digital cable channels. We couldn't access our digital channels on our TiVO Series 3 without a cablecard plugged in. Maybe it's just Comcast, who knows.

Of course you need a DVB-C card for testing the digital channels. But for testing analog chnannels you can use the well known analog tuner cards. The tuner is deciding, which channels can be viewed - not the cable itself.
