i just switch from PC to mac about 2 months ago. 1 thing i notice is that the graphic quality on the mac is very bad compare to the old DELL i used to have... i have no clue why, i thought MAC should be very good on grapics. but when i view the video on quicktime or windows media player on my mac. everything seems to be crappy and not smooth. what could it be? bad video card? need to renew codec? need more RAM? My comp is Powerbook G4 1.67GHz, 512 MB, ATI Mobility Radeon9700, 128MB VRAM Quicktime Version 7.0.1 Windows Media Player 9.0.0 thanks a lot in advance!
