YouTube not loading

No. It works fine with everything else speed wise. It's just when a YouTube video is in high res that it will load 5 seconds and then just sit there doing nothing. I tried to re-sync it with my laptop but that didn't do anything to solve the problem.
Reboot the device, hold down sleep button and home button until you see the white apple on the screen. This usually gets YouTube working again for me when this starts happening.
Just tried that and it was still the same. I have no problem with my iPhone and YouTube that actually loads up instantly. The iPad though isn't going past 5 seconds. I just pulled up the same video on both devices and it loaded on the iPhone but not on the iPad.
Ok. This won't load up

On my iPad but will on my iPhone on the same router.
This will load up on both.

There is a big difference in the res of the videos, but everything else is the same - it just won't load up on my iPad.

Hmm that's odd that it works on your iPhone but not the iPad. It loaded up for me on my iPad. Anybody else not able to load it?
I don't think it's a problem with the iPad, itself. I think that the iPad, much like the iPhone, is tuned for lower-bandwidth environments, such as cellular networks. I can only say this because, looking at the transfer-rates of youtube compared between my macbook and ipad, my macbook gets ~293 KB/s, while the iPad streams at 66 KB/s. They're both requesting the same youtube video, it's just that the iPad, for whatever reason, wants to pull data at nearly 20% of the speed that it *could* pull at.
Anyway, I think that the tuning for lower bandwidth situations also makes it a bit more sensitive to packet loss. When the iPad (or any node, for that matter) sees packet loss, it thinks that the server (in this case, youtube) is pushing too much data for the network to handle. As a result, it drops the TCP window size, which can cause a whole slew of algorithms to slow things down. I often see a drop in the TCP window size not too far into watching a video on youtube from my iPad. This correlates with a drop in the data rate.
-This could be caused by the apple acknowledged bugs with the wireless. I've occasionally seen the wireless indicator disappear and reappear, which leads me to believe that it flashes off of the network for a second.
-I think that the tuning for the TCP/IP stack could be better, and allow for a bit more packet loss before drastically dropping the data rate. At the very least, they should accomodate for the fact that I'm using my wireless connection, rather than a cellular modem.
-This could also be caused if you are using DNS servers other than that provided by your ISP. An example would be OpenDNS. Google/Youtube have servers located geographically close to you, and use DNS tricks to figure out which youtube servers to put you in contact with. Typically, if you use your ISP's DNS servers, you've got a better chance of getting Youtube systems that are close to you. This results in lower latency, and lower likelihood for packet loss.
I'm that a fix in the future would fix all or any of these.

Sorry bud ... That all went over my head. You're saying it has to do with my router, I have a link sys wrt300n wireless-n broadband router. I don't know much else besides that. If there was a way to change something about it I'm lost...
I just ran a speed test with the iPhone and iPad.
The iPhone came out with download 3.86 Mbps upload 4.25 Mbps and ping 92 ms.
The iPad came out with download 0.65 Mbps upload 4.24 Mbps and ping 61 ms.
So there's my problem why is the iPads download speed so low. They were both tested next to each other and at the same time. What am I missing?

I don't know if it helps your sanity but I consider Youtube close to useless on my iPad as well as on my iPhone. It is rare I can get anything to play on either device unless I like to sit and stare at the progress bar for 10 minutes. Some videos work but in my experience most don't. For Youtube I always go to my laptop where everything loads quickly even in HD.
YouTube works great for me but on some HD videos, it does take awhile to load while other HD videos work super. For those who still don't know, you can play standard resolution YouTube videos in the Safari browser by going to the main YT site, and tapping on the DESKTOP option at the bottom of the page.
You can't see the videos full screen and only play them in the YouTube browser page but the videos play great. This is helpful for those with slow Wifi or for those who just want to watch standard Res versions of HD videos without waiting ages for it to fully load.

Me 2
I got an iPad last weekend. It pretty much works flawlessly with one exception. Some Youtube, and/or BBC high-def videos stutter. The video starts to play for 3 to 7 seconds and just stops. If you touch the screen, you can start playing the video again for another 5 or so seconds.
I was thinking it was just me and my network. I am glad and sorry to hear others are having the same problem.

Turning off auto brightness helped me
The following tip from another website helped me a lot:
After I did this I watched five videos and in only one case did the buffering not stay ahead of the playback.
Previously I had tried rebooting my router and that hadn't helped.
The following tip from another website helped me a lot:
Turn off auto-brightness. If it didnt work for so many users, we wouldnt believe it ourselves. To do this, tap Settings, then select Brightness & Wallpaper from the left-hand pane. Slide the auto-brightness option to off.

Adjust brightness upward
I wanted to note that further testing has shown it is more effective for me to adjust brightness upward. From appletoolbox.com:

Adjust brightness upward. Likewise, this issue can sometimes be resolved by simply adjusting the iPads brightness level upward and off the lowest setting. To do this, tap Settings, then select Brightness & Wallpaper from the left-hand pane. Slide the brightness bar upward, then wait 1-2 minutes and check for an improvement in signal strength.*Speculation holds that a power delivery issue associated with the screen brightness affects Wi-Fi.
