Sounds like you need eSATA....
AppleTV does not have eSATA or even support USB 2.0 hard drives without hacking. I could, of course, take it apart and put in a larger hard drive, but streaming from my PowerMac (which has two 500GB hard drives internally) has thus far been the better choice.
Meanwhile, some testing with AppleTV 2.1 has shown me that the photo previews talked about earlier are on AppleTV itself. I thought people were saying the iPod allowed them to preview photos (maybe so maybe not but AppleTV certainly now has a preview of all photos with the ability to view just the photo you're looking for instead of just defaulting to a slideshow like all previous versions of AppleTV. Photos show the date marked on the photo file in preview mode, which is nice. The preview mode is much appreciated and finally lets one look for specific picture to show. Showing a specific picture also overrides the moving 'zoom' effect (whatever it's called) if it was selected for slideshows and shows you the whole picture which is nice since sometimes that's all you want to see.
I just tested some other bugs, one of which I already reported to Apple a couple of weeks ago and clearly they don't listen since it's still broken and should be a simple bug to fix. If you have your screensaver set to come on in say 2 minutes and then start a slideshow of your photos and pause/freeze on one and then wait 2 minutes until the screensaver activates, it'll go to a black screen and then the AppleTV will not respond to any remote key clicks. You then have to force a reboot to get access back, which is especially irritating considering there's no power button, which means you have to pull the power plug (or use a power strip) to reset it.
At first, I thought it was fixed since it looked like it was going to the screensaver (started to fade) and then didn't; it just stayed on the picture I was frozen on and I could exit, but then I discovered this was part of yet ANOTHER overall bug. Namely, I've got 1400 photos or so on my AppleTV and if I select the OVERALL "Pictures" (as in everything) as the screensaver selection, it simply doesn't function properly PERIOD. In the photos case, the screensaver fails to kick in and thus avoids the above bug (if I select a single folder of photos...say 200 photos, it'll cause the above bug). Meanwhile, if I listen to "My Music" and the 2 minutes comes up (music setting ON), the screensaver kicks in and shows photos from my overall collection (also set to random), but it also cuts out the audio! In other words, the song stops playing! If I select a smaller sub-folder (like the 200 one suggested in the previous example), it then behaves like it should showing the song title in the corner and showing photos while playing music. So clearly, there's a screensaver issue in regards to having a large number of overall photos in addition to the blackout problem above with freezed frame photos. These are all repeatable problems and have existed in prior versions of the AppleTV 2.x software.
Internet Radio was working in 2.0.2 but it wasn't advertised. It didn't work in 2.0. In 2.1 as already mentioned by someone, it actually says "Internet Radio" for a station and shows a radio tower and in the list mode it shows broadcast type icons for radio stations and new purple and green icons for special folders and regular music files. Sadly, Internet Radio stations don't appear to give the SONG name for the song or show currently playing. This IS available in iTunes and will also appear in SIGNAL if you use that program to playback Internet Radio over Airtunes. SIGNAL will also attempt to find album art for Internet Radio songs playing, which is really cool, IMO. Apple should consider such options in a future AppleTV update. They could easily show the 'radio tower' on one side of the screen display and the album cover on the other side. At the very least, they should show the current song name, if broadcast, IMO.
There's still no "Year" data given for music files when selected in My Music. That's kind of annoying, really. There's no reason why AppleTV shouldn't give the full meta data available for a given song or album. At the very least, it should give the year for an album or song, IMO.
There's STILL no search for your OWN music, just Apple's iTunes store (like you don't ever need to find music in your own collection quickly?). I've heard there IS one for the iPhone/Touch interface, but if they can include an AppleTV interface search for their own iTunes store for music, why can't I search my own music library for songs? I have 375+ CDs in my library and therefore 4700+ songs so a search would be helpful.
I noticed in Photo mode that the "up" and "down" pushes of the remote don't DO anything at all. It seems to me that would be a perfect place to have 'zoom' functions for the photos. You could then push the play/pause button to enter a 'cursor' mode to move around the zoomed picture and again to go back to a normal view. That's a basic sort of function in something like XEE (although obviously not with those controls) so why not in AppleTV? Let's make this a GREAT photo viewer, not just an after-thought! The photo preview is at least one step closer.
Wish Lists for movies are nice, but I can't help but notice that in the little review/summary section that there is a RATING and that there are COMMENTS indicated. Well, how about a way to READ those comments on AppleTV Apple??? I don't want to have to go upstairs to read them on my Mac when I'm browsing for a movie to rent.
Still no visualizer for music.
