I have a streaming Netflix account that I watch on my TV via my Sony Blu Ray. The Netflix menu on the Blu Ray really stinks since you have to use the remote keypad to punch in information. Searching for something to watch on a laptop or my Samsung tablet is great. Has anyone bought a cable and used their tablet as an input source to a TV? I think I would need to set the input on the TV to A/V. Are there disadvantages to this method?
