That's incorrect. Think about it--DV and DVDs are both compressed, and both the same resolution, and both are Standard Definition. If they weren't, then HD-DVD and Blu-Ray wouldn't be "True HD," because they're compressed. Neither would anything broadcast on any HDTV channel. Compression is used by broadcasters in both HD and SD, and nothing in the technical standards of HD or SD has any limitations on compression. Further, DV meets the required resolution for SD (regardless of the chip in the camera), and HDV meets the required resolution for HD.

I understand your frustration at the idea that any crappy image can be upsampled to HD and, technically, be HD. The FCC is forcing television stations to conform to HD standards, and over the next several years, all stations will comply to these standards, but some of the smaller ones will just be upsampling their SD broadcasts to HD. This irks me too. But that's the way it is, it's true.
