What is the least complicated way to connect my laptop to my 990 to view internet content? Basicly using the HT for audio and video instead of the laptop screen and speakers.

My Sony TV is not an internet ready model and my BDP doesn't have the ability to accept an internet signal.

I have coax and cat 5 from the main house computer/wireless modem location run to HT equipment location for any future use including this if needed.

I thought if there is someway to work from a laptop in front of HT setup with the keyboard would be much more convenient. I would prefer not to have it hardwired from the couch but that would not be out of the question.

Thanks for any help
