Update your flash to 10.1 + to utilize your GPU instead your CPU..
It's odd.

My Single core computer 2.26Ghz with X300 ATI still able to run HD but slight lag. Still watchable.
 
Flash always sucked on Mac OS. But it shouldn't be so bad that you can't play videos properly.
 
So I'm sitting here with nothing to do and I decided to watch some Tonight Show but I can't
That's because you should be watching Letterman, not Leno! :D
I can't test the video, as NBC most likely not allows outsiders to watch their precious programming.
How far "outside" ARE you? :D
I'm not sure how to check the flash version?

the MBP can't handle playing HD from NBC's flash player. Really angry right now
It works perfectly fine on my 2 1/2 yr old MBP. Your MPB CAN handle HD video. You simply have a technical problem that needs to be diagnosed and resolved. There's no need to be angry.
 
Do you use firefox? could be the browser saving the tabs every 5seconds thats making the video choppy.
 
Well my Mac Mini with 9400M just played the HD quality video from the tonight show on my 1080P monitor, so your MBP with 330M twice the ram faster processor and 1280x800 resolution should handle it no problem.

Do you have a lot of other apps running in the background or a lot of tabs open in Safari? If you are running out of free RAM it would stutter because it can't buffer properly as HD video requires a bit more memory than SD quality.

Definitive answer:

- Pull up Flash-based video - doesn't matter which site.
- Right click on video, Settings.
- Uncheck "Enable hardware acceleration"
- Restart browser and try again.

For Netflix: Make sure you're not trying to run 1080p Netflix vids with that 13". They'll run, but not well. 720p should be fine.
 
Ok I've done everything that was said and recommended except for the reinstalling of the OS and while it's a lot better than before (It's watchable now) I still feel like it's playing slower than it should be it just feels laggy and it pauses for split seconds sometimes and jumps. I'm going to use my camera to take a video later and put it up to see if anyone else experiences the same issue. I was going to take a trip to the mac store and just use one of theirs to play a video on and see how it was but I don't want to have to make the trip twice if I wind up needing a repair or something.

I also discovered it's really laggy when there's flash ads on the screen the scrolling gets extremely choppy.
 
I installed Windows 7 in bootcamp. Everything seems to work a lot faster, streaming, and even the typing of the text doesn't lag anymore. Is there something wrong with my OS X

No. Windows is just better.
 
Theres definitely something wrong with your computer. I can run the HD streams from all the broadcasters with zero lag on my 2.4ghz C2D Unibody.

Also, I've never seen Netflix lag on an Intel machine, so something is definitely going on there.

Same here no problem with mine and I use Netflix all the time.
 
It does sound like something is borked with OS X since Netflix is even having issues. I mean, I can run that on my Wii with zero rebuffering and that's on a 1.5mbps connection. It's got to be some kind of graphics issue since Flash and Silverlight (Netflix) are having issues.
 
Just install windows, everything runs better on that side. I still don't understand why there is such a huge performance difference from Flash on Windows to Flash on Mac, I'm sick of the 1-3 second delay whenever I want to make a flash video full screen.

Flash was designed for Windows and not Mac OSX I think.

Adobe never bothered to put enough time and effort into coding and optimizing the flash runtime on Mac OS.

There is no question of "design" here. It is not like they built a part for the space station that went up and now is unmodifiable.

It is software. It shouldn't take too long for a company like Adobe to completely rewrite their runtime for MacOS. The two platforms have been running on the same hardware for 5 years now, so that is not an excuse.

While there certainly are technical differences between MacOS and Windows, the bigger problem is that Adobe just hasn't put enough resources to work on making flash work consistently across all the platforms.
 
Well I'm in the process of reinstalling OSX just to be sure
 
I'm having the same problem as the op. I can play abc pretty well but netflix/hulu/nbc lag and the audio is not in sync. The only difference is that I'm using a late 2007 white macbook and I'm almost out of ram even after I transferred a tons of pictures and things to an external hard drive.

Just to make sure: RAM is short for Random Access Memory and the place where running applications and open files are temporarily stored in, as RAM is quite fast (5 to 6 GB/s with DDR2 SD-RAM). The HDD (Hard Disk Drive) is the place to actually store files permanently, including applications and the OS (Operating System).

When one speaks of RAM, the term "memory" is used too, but when one speaks of HDD, one is better off using "capacity" or even "space".

What Mac OS X version do you use and have you installed the latest version of Flash yet?

And what is you internet connection speed? You can test it with www.speedtest.net or other similar services. Know that ISPs (Internet Service Providers) and SpeedTest will use the unit "bits" to advertise and display internet connection speeds, as they sound faster, because 1 "byte" is 8 "bits", thus a advertised download speed of 16 Mbit/s (or 16,000 Kbit/s) sounds faster than the 2 MB/s it actually might be.
