Has anyone else has a problem with the HDTV downloads? I downloaded the free episode of Heroes to see what the quality was like. One the HD version of the show had downloaded it completely disappeared. No where to be found, not in the trash can, no where in spotlight. Which I thought was weird, but thought it must have been my fault, and afterall it was free, so nothing was really lost. (The standard version downloaded perfectly.) I then decided to buy the first episode of Grey's Anatomy, Season 4, and just as it completed downloading, once more it disappeared. I have searched high & low. Once again the standard version has downloaded perfectly. It's really annoying that my money has basically been wasted (especially as I already have all of Season 4 from iTunes. So that's $2.99 down the drain! Also, anyone having problems with how music videos show up in Grid view? They are all in (lots) of unknown albums, and just look horrid. I wish iTunes would give them there own tab again, like it used to be (iTunes 6.0??) Other than that... I love the new grid view, it looks awesome. The visualiser is sweet as & I think the genius side bar is, well, genius! Anyone have any ideas on what to do about my HD missing shows? (Obviously report it to apple).
