Using Win 7 MCE with digital cable

My cable company, Insight, converted to digital a few months back. I have my main TV connected via HDMI/DVI to the cable company DVR and all is good, extended cable and premium (HBO) in HD. I have the coax straight into a newer Samsung 32" HDTV and I get a slew of new channels and subchannels (e.g., 8-1, 8-2 etc) in HD but no useful cable guide. Insight provided a DTA for a second, older Samsung and I get the extended basic lineup I had before the digital conversion, in SD I guess with no useful cable guide.

I'd like to make use of a Win 7 netbook and USB QAM tuner so that I can have my cable channels on MCE along with slingbox view of my premium channels on one TV, without changing sources (my wife cannot handle that). Assuming I use the new Samsung can I run the cable coax straight into a USB tuner with no cable card and get all the digital channels/subchannels displayed in MCE? If not , why not? If my Samsung HDTV has an internal tuner (no cable card either) that decrypts these channels why can't I buy a USB connected similar tuner to use with Win 7 & MCE?

Also, the netbook will not pass the Digital Cable Advisor due to its inadequate Intel integrated graphics card. Here is the USB tuner I am looking at:

Avertv Hybrid Volar Max TV Tuner Kit for Windows

Am I stuck with using two sources for the new Samsung HDTV (one for digital cable, one for slingplayer via Win 7 explorer) and tuning MCE to channel 3 0r 4 and using Insights DTA remote to change channels on the older Samsung?

Again, a cable card solution would require me to buuy a new PC as both Win 7 MCE PC's I have are netbook or mini and I cannot upgrade the graphics card. It's Intel 940 GMA or something like that in both Win 7 PCs.

Why doesn't my newer HD Samsung with internal tuner require a cable card? Cable coax connects directly to this TV and I receive all ESPNs, Comedy Central, AMC etc and all digital subchannels.

I used the bypass but the problem with the Silicon HDHR for me was both Win 7 PCs I had intended to use have Intel integrated graphics 950, not enough to use with the cablecard/digital CATV service. Silicondust box and literature at time made no mention of minimum graphics card requirements.

I have two Ubuntu machines and would use Myth but since MCE failed I did not venture to tackle a Myth setup. Last time I did it was very time consuming. Are you saying my preferred USB clearQAM tuner with myth would result in my receiving all encrypted (e.g., ESPN) but non-preium encrytped (e.g. HBO) channels?

I like Linux but MCE is a good product and Win 7 is not horrible like Vista.

So will the USB tuner I posted first allow me to receive these via my Win 7 MCE?

Avertv Hybrid Volar Max TV Tuner Kit for Windows

I received the Avertv Hybrid Volar Max TV Tuner Kit for Windows and set up Win 7 mc. I am only receiving the aBC, CBS, NBS, PBS channels 19 total. On my "cable ready" Samsung tv I get a host of other channels including tnt, espn, comedy central, hgtv, hallmark etc.

Why does the Samsung internal tuner receive all these channels, it has no cable card just straight in coax, and my Aver tuner only 19?

time consuming for 80 plus channels but it works. Unfortunately, when changing monitors Win 7 hung & I had to do system restore to get a proper reboot, thus lost all my manual MC channel work which took over an hour.

I am getting a new PC with better graphics so HD not so choppy. Any way to transfer the MC guide & channel info so I do not have to manually set up 100+ channels?

Anyone know how to download the MC guide once the QAM channels have been successfully added?

I tried the usual method but nost QAM channels say no data available.
