josefresco asks: "I have one goal for HD streaming: archiving. As we all know, the Comcast DVR box doesn't have a whole lot of HD. What can you expect with only a 120 GB hard drive? The thing really should have a 500 gigger or at least a 250. So right now, when the box gets full, in order to avoid the box automatically erasing unwatched shows, I dump the transport streams to my Mac via Firewire. I don't necessarily need to watch the shows on the Mac. At that point, I just want a solution to allow playback of the transport streams from the Mac back to the TV. Enter the Xbox 360. Might this be the answer to my problems? If not, then are there other devices that might be?""We've got the Mac connected to the TV right now, so technically, we can watch the streams in full high def in the current setup. You just can't control the Mac with a remote control unless you buy an infared device. Besides, when we move into our new house, it is doubtful that we'll have the Mac in such close proximity to the TV, so I really need an intermediate device (or a media extender as they're starting to be called) to playback the files off the computer.
It is unlikely that the Xbox 360 will work with the Mac out of the box, so it will probably require some hacking. It's annoying that it won't allow you to see SMB shares on the network without any special software. You either need an XP Media Center 2005 machine, or an XP machine with SP2 and something called 'Media Connect' installed in order for the Xbox to communicate with the PC. If the thing could just read SMB shares off the network, I would be golden.
There are a few devices out there that apparently fill this gap pretty well. They're dubbed 'networked DVD players', so they're essentially a DVD player with an Ethernet connection. They all have some bugs though, so I've been reluctant to jump on any of them.
Thoughts? Is the 360 the answer to my problems, or do I need to start searching in other directions?"
