A:AnswerThis could be quite difficult. I don't have a DTV box to test regrettably. By searching their forums I see a lot of no answers about transferring recordings. Some of the HDMI ports are in, some are out. Often the USB ports may be locked. Another issue is that a lot of HD content is digitally protected and even if transferred may expire. Short story, if you buy anything, buy locally so you can return if it doesn't work. I would contact DTV before I put a lot of time and money into it to see if it's even possible.
A:AnswerIt might. I'm not sure about your setup. If you are trying to connect to a D9 serial port through a USB adapter, it might work. It requires a USB 3.0 port but will work with a USB 2.0. Anything less (like a USB 1.0 adapter) and it probably won't work for you. If you have a D25 serial port, that might be alright. Just don't plug it into the D25 parallel port (if you have one) because it won't work.
A:AnswerYes, but not very well. It can display video, but you will be better off using a lower video resolution than it recommends, as the frame rate I got out of it was unusable for what I was using it for, a media computer.
A:AnswerDVD players will most likely have a HDMI output port on it so you can just use a HDMI cable from the DVD player to the tv. But no it can not because for this to work on a computer, the computer needs to download special files for this to work. And you cannot put these special files onto the DVD player. Sorry mate
