For so long I've been looking high and low to find a way to be able to watch YouTube videos smoothly on my iMac G4. I'm an avid YouTube user and I spend most of my time on there during my down time (This is on my 2012 MPB). So far, I haven't be able to get videos to play very well, without having to download them. I've been trying out both YouView and MacTubes. Which pretty much everyone in the PPC community agrees seems to be the best way to watch videos. My issue is that its never works for me. I never get a smooth video, now matter how hard I try. It normally gives me one frame a second with maybe a half a second every now and then of smooth animation. Though, the audio is running just fine. Keep in mind, this is the only program open on my computer. That way I have as much RAM and CPU power open to watching a video. I've heard how people are able to watch 480p video on 800MHz machine. Yet here I am with a 1GHz G4 and on a good day able to play 240p. My Specs: iMac G4 from 2003 running OSX 10.5.8 1GHz G4 1.25GB RAM 32MB VRAM Wired Ethernet As far as I know the internet connection is fine. I living in a dorm currently. When I hook up my MBP I can often get somewhere between 80-120 down. On a bad day, 30 down. Granted the MPB has Gigabit Ethernet. Though I would then assume my iMac is being pushed to its limit with how much its Ethernet can take in and how much the CPU can go through it all. Is my computer just too under speced to play youtube videos at a decent resolution (decent being 360p) and the 800Mhz 480p stories are a lie? Do I need to reset/clean/install/reinstall something on my computer? I'm really confused at this point and it's starting to frustrate me a bit. Please help.
