The three in question are -
Magic MTV 3600TD
As far as I can see, they are all the same price, do much the same things, and are feature equal other than maybe hard disk size.
1: In anyone's experience, is one brand better than another?
I note that in all three the firmware upgrade path is via USB ports on the rear panel ... would be nice to have such on the front similar to most DVDR's, but also note that they have an ethernet port yet the manuals I've found don't say what the port could be used for. The exception is the Magic unit, which purports to allow an internet connection and access to some RSS feeds and weather etc via pre-programed buttons on the remote.
2: Could any of these units be also used to connect to the internet, or a home network for other media, e.g. music?
Looking forward to your views.
