I have Time Warner SA 8300HD.
Do I need to have a QAM card to catch the signal from 8300HD?

Thanks for the replies guys.
Here is what I don't understand and maybe I should have started with this.
Why can't one just connect a PC Tuner card to 8300HD, just like TV is connected to 8300 and capture what ever channel the 8300 is currently on?
Is the signal coming out of 8300 unencrypted, I mean how else is the TV getting the reception?

You can, just tune your tuner card to what ever channel your 8300 outputs on over its coax output(either channel 3 or channel4) as if the signal was coming from an antenna.
However, the signal your receive from either the coax or S-Video output is in NTSC SD 480i resolution regardless of the resolution of the channel the 8300 is tuned to.

The only time you ever use the tuner in your TV is when you take the coax from the wall and plug it directly into the TV. The same goes for a PC tuner; the only time you use its tuner is when you take the coax directly from the wall.
When you use a STB/DVR, you are using the tuner in that STB/DVR, not the tuner in the TV. Once the signal is tuned, demodulated, and decoded by the STB/DVR, the output you get via HDMI is an encrypted, uncompressed picture signal at about 1Gbps (125 Megabytes/s). The TV decrypts that HDMI signal, applies its built-in video processing, and you see the result on the screen.

Are you talking about a tuner card with a composite/S-Video aux in? If that's available to you, you could do that (obviously with the caveat that you won't be getting HD, but the box will convert to SD and letterbox the picture). If you're talking about using the RF in - no. I don't believe the SA 8300HD/HDC has an RF modulator integrated into it, so that wouldn't work.

Since I do want to capture HD, here is what I still don't understand/know. Are there cards that will capture HD via hdmi inputs? And is the TV really decrypting the HD data? Can't that same decrypting technology be used in a PC card? Do those exist (expensive maybe)?

There is a board that apparently will capture via HDMI, but that's misleading - if HDCP is used, it can't capture, and HDMI devices are required (through the license agreement) to use HDCP encryption. There aren't currently devices that can capture via HDMI, because HDMI Licensing *will not* license such a device (they don't want such a device). You could use the Hauppauge box I mentioned earlier to capture via component - and if the HDMI output is the only one available, you could probably use an HDFury2 to convert to component out. However, it requires a computer, and it's not cheap (somewhere in the $300 neighborhood, I believe - not prohibitively expensive, but a bit much for a lark).

That would defeat the point, wouldn't it?
The whole point of HDCP encryption on HDMI is to prevent recording to the PC, and the unauthorized redistribution [by some] that will result.
If you are serious about this, you might consider the Hauppauge HD PVR ( review ). This product can capture 720p or 1080i component output, digitize it, and then encode it with MPEG-4 AVC on the fly. It can then be viewed on your PC. There is obviously some quality loss, but at the highest quality setting (AVC @ 13.5Mbps), most do not seem to notice except on motion-intensive content (sports) and/or larger screens.
Personally, I just download recordings directly from my TivoHD with a web browser . But you can't do that with a SA DVR. And even if you had the same DVR, what you could and couldn't download on a stock unit would depend on the CCI (copy control) bits used by your cable provider.
