I have a mac pro 1,1 just as you do, specs can be seen in my signature.
You should have ZERO issues playing anything in HD. I do it on my 23" apple cinema display and it handles HD absolutely perfectly on youtube or any downloaded video files also play perfectly in HD using VLC or Quicktime.
If I were to guess, it sounds like a graphics card problem... but thats purely a guess. I could play 1080P video on the old card that came in this and that was a low end ATi $50 4650 (I think?) card that sucked badly.
Could also be a codec problem. 3GB ram is a bit low, but it shouldn't effect the ability to play back HD video at all being that low.
Hello,,,sorry for the off topic but this is really urgent
Yesterday my Nvidia 8800GT died, and now my Mac Pro 1,1 is dead without Vga.
i noticed in your signature that you have a GTX 570 installed,,,i suppose this is a Pc flashed with 32bit or 64bir EFI or what?
Do i need to flash my Mac Efi 1,1 to 2.1 or or should i leave it so?
Please answer anyone who knows about this issue....
Thanks in advance
