We're experiencing the same thing.

We are shooting in HD now (HUGE pain in the ass, it's a tapeless format, so you capture to memory cards or a portable hard drive, then transfer the 75 gigs worth of files to the PC and back it up on the RAID array).

But HD is very unforgiving. Not only is it unforgiving to the model -- every ass hair is shown in exquisite detail -- but focus becomes a very sticky issue... you have to have it in precise focus or it's really noticeable, unlike regular DV video, where the lower resolution will cover minor focus imperfections. And the camera's viewfinder or built-in LCD display isn't capable of displaying the high resolution -- not enough pixels -- so to check your fine focus, you have either use an external monitor or the "focus assist" which blows up a small portion of the image on the LCD display to refine focus.

The main reason we started shooting HD content was to have the highest quality for the assets going forward... people may not want it now, but in 2 or 3 years, it might end up being a standard... so we figure the more assets we capture now, the better off we will be.

But... we will most likely continue to downconvert all of our HD material to SD for release on DVD or on the websites. And once downconverted, it looks pretty similar to regular DV content.
