Is there anyway to increase the buffer size on internet video viewing like you tube? My internet is not fast enough, so if I try to watch HD internet video, it's very choppy. If I can put it on pause for a few minutes and let it buffer, then viewing it wouldn't be so choppy. However, it seems that Tivo would only buffer a small amount. So if I pause for 10 sec, vs. 3 minuts, it's still the same amount of video buffered.
