I would like to purchase the WD TV LIve Media Player, but I don’t want to waste my time if it won’t work with my current setup. I am running WIndows 7 with a Linksys WRT54GL router. I would like to use wi-fi to view photos and small avi videos stored on my computer on my HDTV two rooms away. Will this work without being painfully slow? I would like the transition from photo to photo to be snappy. I understand that I would have to purchase some sort of USB dongle to receive the wi-fi signal. Thanks for any help.
