Ok so heres the overall breakdown of the problem. Computer 1 Windows 7 Ultimate 64 Bit Main desktop, games, music, TV shows. ASUS PN5-E SLI Core 2 Duo E7500 2.93 GHz 4GB DDR2 800 Ram GeForce 8800 GTS 320GB HD Main Drive 320GB HD Games 500GB HD Music 1TB HD TV Shows Computer 2 Windows 7 Ultimate 32 Bit Dell Inspiron E1505 Laptop Intel Centrino Duo 2.0 GHz 1GB DDR2 266 Ram ATI Radeon Mobility X1300 100GB HD Computer 3 Windows XP Media Center 2005 32 Bit Core 2 Quad Q6600 2.40 GHz 2GB DDR2 800 Ram ATI Radeon HD2650 XT I recently swapped out motherboard, ram and CPU on computer 1 from an old config to the current setup previously stated. The tv shows drive hasnt changed from the old setup but now whenever I try to stream an episode of a TV show from this computer to ANY other computer, after a few seconds there is lag, it goes away and then comes back after anywhere from 30 secs to 1.5 mins. It happens whenever I try it on any other computer, Laptop, HTPC, other computers in the house etc. The desktop itself can play the videos fine with no problem whatsoever. They can even stream movies from the HTPC without any lag/problem whatsoever. This problem didnt exist whenever all PCs had windows XP installed (Laptop had media center, desktop had XP Pro and HTPC had/still has Media Center). I havent installed 7 yet on the HTPC for fear of the ffact that the problem may follow me there as well. I consider myself very savvy and able to fix almost all problems but I'm not sure what to do in this situation. I havent set up a homegroup yet because for some reason the functionality seems broken on the laptop, so I just made standard shares across my network. Any ideas/thoughts/inputs?? All hardware drivers have been updated to 7 verified 32/64 bit versions so I dont think that could be the problem.
