Hello all! Well I, like many others have converted to mac from the dreaded onslaugh of the x86 world! My first mac is a dual usb iBook (now overclocked from 500mhz to 650mhz!) 384mb sdram, 80gig hdd and dvd/cdrw combo drive. Now before overclocking and after overclocking ive had some very weird issues with DVD playback. Either one of the following will occour and in time instnaces both will occour. a) The video feed is very unstable, the image flickers and cant stay still for long. b) The image will gradually get brighter and brighter and brighter and then dim..... then get brighter and brighter and brighter.... then dim... continuously. Now i've done the following, Copied a friend's copy of the dvd playback software. reset the PRAM tried it on another TV Tried another AV cable Tried several DVDs If i play a movie off Mplayer or quicktime there arent any issues, its just on dvd playback. Has anyone else had this problem?? And if so how have they fixed it?? Thanks alot in advance!
