[quote=VirusKiller]Apple TV 3 with Plex and the brilliant PlexConnect "hack".
Does this allow ISO playback. I had considered Apple TV, but ruled out due to lack of support for ISO.
Not sure. Doing a little Googling "plex iso playback", I've seen yes and no answers and also someone who claims that the Roku XS will play ISOs in conjunction with Plex. More investigation needed... [/quote]
Yes, I've been trying to investigate as well. Seems I could definitely play .iso using a hacked Apple TV 2, but this also now seems a lot more expensive option and only supports 720p (although not an issue for DVD playback). Not clear at present if Plex will work with my NAS either, but it seems it may not as I've seen a mention of requirement for X86 CPU. I have 2 kids and a few iPads at home, so streaming options to iPads would also be popular option for them with Plex if it works. I will try out on an iPad today.
My understanding was that .iso format is best for DVD movies. What are you using?
