I usually have the PC download videos (cuz it's a desktop with much more storage space than ibook) and have the ibook open it from all over the house so i can watch anywhere! Unfortunately, it lags! (it plays normally but skips a second or two then back to normal every 2-3 minutes) Information: I have an SMC wireless router, WindowXP PC, and an ibook. PC *wired connection* to Router. Ibook has a wireless connection to router. I use VLC on my ibook to open the video (.avi - around 170mb file) from my PC harddrive. my brainstorming tells me the possible scenarios (but i'm not certain)... 1) ibook - low transfer rate (3 bars wireless) 2) VLC creating problems 3) SMC slowing down due to too many ports open (I use azureus bittorrent) if u have any tips that can eliminate these problems shoot! thanks in advance!
