I'd have to agree. I've played a number of the 15-ish minute Machinima videos on Youtube and they stream fine. I'm not saying that people aren't having streaming issues with Youtube, but it isn't "just" Youtube's fault.
If anything I would put wagers on the issue being a combination of their WLAN and N7. Possibly also some people have bad DNS server settings.

I had the same issue also, here is what I did:
I read somewhere that some of the older android OSs had a problem connecting and staying connected to higher wireless N routers. Now my droid 4 phone connects just fine but its on an older OS then the nexus. So I set up a guest wireless account and instead of having WPA2-PSK [AES] security on it I set it up to have wpa-psk [TKIP] security which is supposed to be easier to connect to for older legacy devices and now my Nexus 7 is able to stream video without issues (play store items, youtube, ect), even HD format. Now the only downfall is that you can only achieve 802.11G speeds with this setting so hopefully, if this is the issue, they get it sorted out soon so we can use the higher range and bandwidth of 802.11N. Like I said earlier my phone is version 4.0.4 and works fine on the main wireless account with WPA2-PSK [AES] security and higher speeds so whatever the issue is it seemed to come from the newer OS...
Hope this helps!
Got to disagree, it doesn't do it all the time, but there are times when YouTube is unusable for me. Strangely though, it will sometimes only be certain channels that buffer, others will work fine. I thought it was my wireless connection because I have the same problem on three different devices, but according to speedtest and a couple of other tests, my Internet connection is excellent. It doesn't happen as often on my galaxy s3, but Nexus 7, and asus tf101,struggle with it fairly frequently. I've tried everything I can think of, uninstalled updates, reinstalled updates, reset router, reset wifi password, factory reset all devices etc etc. It still happens a couple of days a week.

If nothing else, run the namebench test on one of your computers and then change the DNS setting on your router (make a copy of your current DNS settings first obviously.)
If you don't see any improvement in your browsing/streaming speed, you can always set it back to what it was.

I agree this is a very good idea but it does only cover one part of your video streams pathway home...
Pretty sure I acknowledged the other parts in my earlier post.
The part you quoted me on was specifically in response to Ryano89 commenting that streaming seems random, working sometimes but not others. Further, the fact that he said it happens with more than just his N7 and he's already reviewed his WLAN settings kinda made it pointless for me to tell him to just check his N7 or his WLAN settings...

Settings, WiFi, advanced, uncheck WiFi optimization. This finally fixed my issues.
Ugh When I first got my N7 the Youtube video buffering wasnt awful, but lately it buffers so badly I keep giving up on even watching them. I haven't found a single solution online to my problem and since youtube watching is a primary use for my N7 I'm beginning to seriously regret my purchase. It only happens for me when using youtube. TVportal steams very fast and actually the movietube app streams fast as well considering it utilizes youtube to function.
