And that's exactly the problem. Practically every single specialty channel in the US from Investigation Discovery to Lifetime:Real Women to SoapNet to Cartoon Network are in HD. Up here, we have to whine and wait to get them. It's sad, this day and age there's no excuse for anything not to be in HD.It doesn't matter what Discovery Science airs to me. If it's not available in HD, it wont be on in my house. Same goes for Investigation Discovery.
