DSLRs and misinformation

I see there's a lot of misinformation out there regarding DSLR cameras, specifically from video people. Generally they say things like 'the compression is terrible', and 'not broadcast quality' blah blah.
HDV for instance, is not the best quality either, and it gets used on TV (not a lot, I know). Same with footage from things like EX1s and EX3s. These people are essentially spreading stories to make people doubt the quality of these new systems that they tend to not own. They are trying to artificially create a 'pro-quality' distinction between DSLRs and their kit.

5Ds all the way down to 550Ds record with a 47megabit per second data rate. For a basic comparison of how much information there is, HDV records at either 19 or 25Mbps... about half the information! Even EX3s on the 'high quality' setting only record at 35Mbps, meaning DSLRs record on average a 3rd more data than even EX3s. Of course there are tons of cameras that record at much higher bitrates, but then we're looking at really expensive cameras. HDCAM or anything that compresses to a 4:4:4 format, or anything that records a raw image will definitely beat these cameras both in edge detail and number of line-pairs recorded. But they are significantly more expensive for very little perceptual gain in quality.

This 'pro' 'non-broadcast' stuff just annoys the hell out of me because of how blatantly untrue it is. H.264 doesn't make 'square blocks' on a high-resolution monitor. I've checked both on my 24' full HD screen and a £20,000 Cinetal colour grading monitor. It's nonsense.
You might have heard 'House MD' recently shot an entire episode on 5Ds? Don't tell me that the top people working on the top show in the world would shoot on something that was 'not broadcast quality'.

All that misinformation aside; there ARE issues with these cameras. It's too easy to set high shutter speeds, so people tend to slip-up and record jerky motion. It does have a problem with moire - creating strange swimming patterns with thinly-spaced repeating lines (stripy shirts, brick walls etc.). But note that this problem is not limited to DSLRs, all video cameras get it to a point. 10 years ago, it was just a rule... moire happens, shoot around it. Now at least we can throw backgrounds a tiny bit out of focus to avoid it. Aliasing (stepping on diagonal straight lines) is also a problem... but not much of a problem at 1080p. It is a more significant problem at 720p. Buy a cheap camera (550D) and buy an L-lens with the difference you saved on a 7D. When Canon eventually release a video-optimised camera based on a larger sensor, you'll sell your 550D for a fraction, and still have the good lens. If the lens doesn't fit, L-lenses have good resale value. Win win.

Just my thoughts on what's real and what is misinformation. If I'm significantly mistaken about any aspect of this, let me know – mistakes are where we learn.
