NTL box to HTPC and Sky

The sweetspot video processor will capture component, RGB, multiple s-video or composite RF. From lesson 101, simple application of signal to noise ratios, any noise is amplified and requires more processing to clean it up and that adds artifacts, all waveform conversions have a SNR. The cleaner the signal the better. The source is RGB, stick to RGB, if the source is YUV, you get the idea its not rocket science. The main drawback of RGB is the sync control, not bandwidth IQ.

I know that, but rgb through 3 rca cables is a type of component.

Its four cables, R G B s

No conversion. The combined H/V sync comes from the scart, in component the sync is in Y.

And even sync on green isn't component, as defined by discrete colour channels. Different lower voltages and it doesn't like transmission distance, like component does. It's not the same, here's a standard conversion matrix. The sync has to be added.

RGB>YUV

Y = 0.299xRed+0.587xGreen+0.114xBlue

U= -0.299xRed-0.587xGreen+0.886xBlue

V= 0.701xRed–0.587xGreen–0.114xBlue

YUV>RGB

Red = Y+V

Green = Y–0.195U–0.509V

Blue = Y+U

That sounds much simpler, would the "Hauppage PVR-500" or the "Fusion HDTV DVB-T TV Tuner Card" be up to the job?

Are we saying that this solution will give the best picture quality for both recording/watching as well as audio or is there still more thinking to do - ideally I'd like to get the setup right the first time round.

Yes that would work fine.

The Nebula are popular, there is a software release for the BBCHD trials if your one of the lucky ones near the transmitters.
 
I've decided something along the lines of:
  • AMD Athlon 64 3800+ 64 bit 512k L2 Cache Retail (2.4GHz)
  • Asus A8N-E AMD Skt939 nForce 4 Ultra
  • OCZ Premier 1GB DDR PC3200 400Mhz CAS 2.5
  • Gigabyte GF 6600GT SLI 256MB DDR3
  • Samsung SpinPoint P SP2504C 250GB SATA-II 8MB Cache
  • Plextor PX-760A 18x18 Dual Layer DVD±RW ReWriter (Just because it can read/write CD+G)
  • HDA Digital X-Mystique 7.1 Gold PCI Dolby Soundcard
  • Fusion HDTV DVB-T Dual Freeview Digital PCI TV Tuner Card
  • Seasonic S12 430W Silent ATX2.0 Power Supply
  • Silverstone LC17 Case

Which comes to something just over £700. I'm assuming that would be fine for the setup I've "attempted" to illustrate in the previous posts?

If there's anything obviously wrong - please tell me... or anywhere where I can save some money without compromising quality...

Is there another PSU worth recommending? I've got a S12 600W PSU myself and it's quiet but the cable management is poor - is there another efficient PSU that's modular, efficient and quiet at the same time?
 
Kbc I have emailed a pdf to your gmail account on how I hooked up my ntl to my htpc and what hardware I used hopefully it will be helpfull :)

Looking good. Wireless keyboard inbuilt mouse? Have a look on the auction site for a BTC 9019URF, I've found them good value.

OK! I'll check that out... Are there any other wireless keyboards with in-built mouse worth considering?

Thanks... very useful Chaos! I assume the Fusion TV card I've chosen will be up to the job, as you've only listed the Hauppage cards? I assume there's no better alternative than the MCE remote control?

Yeah the fusion card should be fine as long as it has the inputs you need and is mce2005 compatible. Not sure if theres any alternative remotes havn't really looked as I got the Microsoft one.
