Got mine working, awesome!!!
I am just appalled at all the complaining and fighting going on this forum.... But putting all that aside, I want to thank those who are posting and helping users out here, and I want to say something before posting my experience.
For those who are having problems, frustrated, angry, etc... Guess what? You are HACKING. No one ever said that HACKING was easy. HACKING requires patience, persistence, and donating your time to something which may or may not work out. Back in my teen years, I remember staying up all night for weeks at a time to figure out how to break into a certain voice mail system that had just been brought out on the market, in the end alerting businesses to the security loop holes in their voice mail systems and helping them become more secure... Those days for me are long gone, and now my new sense of hacking is buying a product like Apple or Nintendo and making it do things that people never thought possible.
With that said, this is my experience.
1st: Jailbreaking the Apple TV is a pain in the ass. Unlike the iPhone jailbreaks, there is a certain disconnect about the whole USB thing. While most forums I've read say to NOT have the power connected, for me, I *HAD* to have the power connected. I'm not sure if it's because the micro USB cable I bought at the Shack sucks, or if it's because I was using my Macbook Pro unplugged (on battery power) - maybe it doesn't provide enough power. So, for me, what worked was to have the power connected when following all the steps, and it now works great every time I need to reboot. Also, make sure you disable the remote on your Mac... If you don't you'll find that Frontrow pops up all the time when you're trying to do the command sequence on the remote to get the Jailbreak working.
2nd: Installation of XBMC went flawless after the Jailbreak. Followed the steps in the guide on their site, and didn't have any issues....
3rd: Stability - not quite there yet. I've seen some crashes and lock ups. I was installing the Facebook photo app, and was entering my email address when the thing just locked up. Of course, this required a reboot of the AppleTV which then required the tethered boot again. For the most part, if I don't mess with add-ons, and don't overtax the system, it's stable but there are some glitches. Another thing, if you're on wi-fi, don't plug the ethernet cable in while in XBMC!! It will lock up! LOL... Duh!
4th: When I switched from Wi-Fi to Ethernet, and rebooted and re-tethered, for some reason XBMC kept telling me that my files were no longer there - do you wish to remove. I ended up closing and re-opening XBMC a few times and then it worked fine.
5th: Playback - I've thrown everything under the sun... VOB files, xVid, DivX, Avi, Mkv, h264, and haven't had any issues playing the file. I did have issues with a 1080p MKV file, it was skipping and stuttering. When I play it on my PC it does the same thing, so I'm assuming that these hi-def movies just aren't quite ready for prime time playback on your average device. I will adjust my download behavior accordingly and go for the 720p ones - I don't even have a 1080p TV anyway, so it's pointless. If anyone has tips on getting 1080p playback to work flawlessly, do tell.
6th: NAS Support - awesome. I'm using a ReadyNAS Duo from Netgear (amazing device BTW!!) - and all I did was add source - browse network, and it found the workgroup the NAS was in and the shared media folder. From there, I added various folders such as TV Shows, and movies. I'm amazed at how easy this is to setup, and also a bit perplexed why so many users are having issues. For those having issues, I would recommend trying to just browse for the folder on the network - this of course means that your NAS needs to be setup for NETBIOS file sharing.
7th: Scraping - ok this one is kind of random... I added IMDB, and also use built in moviedb (fallback is enabled)... It seems to work, but... Sometimes it doesn't scrape the files the first time, I have to close XBMC and reopen and then it finds some more files. I don't know why this is. But for the most part, it scrapes everything pretty well - the only ones I haven't gotten it to properly scrape are my VOB files. QUESTION: is there a way to FORCE scraping without having to quit and reopen the app?
8th: VOB files - playback works, but I am a little confused. It seems like it will only play one file at a time, and I have to open the next file when it's done playing each file, so in a given movie I have to be interrupted 4-5 times... I'm wondering if there is a way for it to just auto play the next VOB file? Also, for some reason, I can't see VOB files except in File Browsing mode, if I switch to Media Browsing, it doesn't show up - I'm assuming because the scraper didn't pick up the VOB file. Is there a secret trick to making it work (i.e. need to name the folder a certain way?? and enable that setting to read folders?)
Overall, I am very happy with XBMC... It does so much, and I'm looking forward to customizing and playing with it. I hope and pray that they come out with an untethered Jailbreak for AppleTV2 soon... Then I can just take it from room to room (it's such a small cute little device).. Right now I'm afraid to unplug it! LOL
