Why? They play the sound perfectly but the image freezes then moves to another image.

These are my System's specs btw:

Windows XP SP3
Pentium 4
CPU 2.3GHz
1GB of RAM
nVidia GeForce FX 5500 256MB

If you need any more info, let me know!

Additional info:

I have a 4Mb connection, and I know it isn't the one causing problems because my dad's computer has no Video Card (only has the one that comes with the Motherboard), 512mb of RAM and a 3GHz processor and his computer runs the videos smoothly. They load at the same time so his internet connecton isn't recieveing more than mine (aside from that, I did a speed-test on his PC and mine and they were both virtually the same).

I guess I'll download the latest flash version and post back. Thanks.

The quality on those things are still garbage.

That happens to me too i uploaded two of my three vids in HD and they're choppy.

@JaggedSac

I think you're mistaking HQ qith HD videos, because the HD videos running at 720p look great.

Anyone have any ideas?

Download the latest version of flash. If that doesn't help, it may be your hardware.
