Thoughts on video over wireless...<br>
<br>
You are going to need near ideal conditions to get DVD quality MPEG-2
over 802.11g. Given that you need to use a wireless connection in
the first place, it seems unlikely that you have those ideal conditions.<br>
<br>
Also consider that you will likely lose your picture whenever a microwave is in use nearby.<br>
<br>
As far as HDTV over 802.11g is concerned, assuming a data rate of
around 8GB/hr, (on the low side, I believe) you would need to push
about 18mb/s of data out to the frontend. I don't believe you can
reasonaby expect to do that with 802.11g.<br>
