I recemtly purchased a G4 at a local thrift store for $10. After repairing the processor and installing and updating os X 10.4 on a 20g drive I added and additional 100g drive for music and videos. The 20g drive read/write is fine and writing to the 100g works fine also. When attempting to view videos located on the 100g drive, the system hangs. when using itunes it must rebuffer every few seconds. I have the G4 on a wireless network with the drive shared using samba. if I view the videos on my laptop (running LINUX) reading directly from the drive I do not experience any lag or system lockup. When listening to music over the network there is no rebuffering (a very slight lag when moving to next track but is not an issue for me). 500m processor 20g HD for OS 100g HD for media Ati Radeon 9000 pro video card 1.5g RAM I have disabled spotlight (noticed errors in the console) and dashboard in attempt to keep resource use as low as possible . Any Ideas would be greatly appreciated.
