The performance will depend on your wireless networks -- but even a typical B network is plenty of bandwidth for a great picture on your laptop.

As to the model your looking for.. be it turner, a/v or pro -- that would really depend on what you want to do, and how you get your current cable tv. Do you have set top box that decodes the signal - or can you plug the cable from the wall into any cable ready tv and get all your channels.

Ie if your using digital cable you would most likely need a set top box to decode your cable.. This would rule out the tuner version of slingbox, but either the a/v or pro version could be used then.

Do you want to also be able to sling the output of a dvr or vhs, etc.. then that would rule out the tuner model as well.

But if your just on basic analog cable 125 channels, etc.. than the tuner version would be what your looking for.

Happy Slinging!
