Buffering Problem with 480P video

For some reason CR streams are only using around 1/3 of my connection at any one time, and unless I wait 5-10 minutes to let it load most of the video it keeps pausing to catch up.

My connection is a 7mb downstream on a very reliable ISP, I have a Vigor 2800 router with data flow monitor, downloading from newsgroups, torrents (seeds and peers allowing) and speed tests I always get the max speed, so why is CR using so little of the connection, it's extremely irritating trying to watch something with the video stopping all the time.

The speedtest is coming up short for some reason but that should still be more than sufficient for 480P playback, 5mbps+ should be sufficient for 720P

Is there anyway I can get CR to use more of my connection?

System specs....

Intel Core2Duo e6700 [email protected]
4GB DDR2
Nvidia 680i Mobo
Nvidia 275GTX 768mb
Windows 7 64bit (using 32bit IE browser).

Again, I get download speeds up to 7Mbps everywhere, consistent speeds as well, I am not subject to bandwidth throttling since this is a business line with a business ISP package, I own all systems on the network and can monitor any and all usage through the router so I'm not leaking bandwidth, just that CR doesn't seem to be taking advantage of my connection very well.

Is your network secure op or are you using a laptop to play the videos? If you are using a laptop you might need a faster router around 5.8ghz to get an faster speed to buffer. I saw your test and it is impressive to be honest but old send out a weaker signal and makes it harder to buffer the videos.

Thanks for the response.

The network is secure, the Vigor 2800 is not Wireless, I have an access point setup for laptop use in the house but I am streaming these videos to my desktop via a wired connection.

are you downloading or uploading anything at the time you watch videos or have to many programs running at once it could be a possibility that has something to do with it. IE downloading torrents or using any p2p while trying to watch videos tends to slow it down.

Nope, definately nothing going on, I rarely use torrents as I don't like the performance hit the network takes, newsgroups are scheduled to for early hours of the morning, as are antivirus and windows updates, system maintanence etc, all programs closed.

Very few processes running in the background, I prefer to keep my system running as smoothly as possible so I keep it nice and clean.

No broswer addons or anything like that installed.

Also just to be sure nothing was draining on the connection my router accurately monitors data flow, absolutely nothing going on.

<EDIT Problem not yet resolved>

I setup QoS limiting on all systems other than the main server to avoid performance issues, for some reason that QoS was only affecting CR streams so I had forgotten about it.
Disabled it and now even 720P plays without issue.

Thanks again for all your help.

Scratch the above, although it did increase CR streaming usage to approximately 5mbps last night today again it's only using around 1 mbps of my connection and the videos are stopping to buffer all the time.

Not quite sure how to fix it tbh.

There are 3 things I see possible at this time as the cause.
1) Your ISP has QoS or another speed limiting method set up
2) During the slow stream times one of the systems (likely the peering point) is overloaded and can't give you the throughput
3) The streaming server is overloaded at times and can't put out enough data

The best thing to try is changing your DNS servers to an open DNS server, which will hopefully switch which server you are streaming off of.

I think option 3 is likely the cause since I can get 100% out of my connection through other means even though the CR streams are having problems.

Also, whilst looking at my dataflow monitor in my rotuer at one point a few moments ago my CR stream was stopping to catch up every 10 seconds or so but it was barely using any bandwidth at all.

I'll do my homework on open DNS servers but I'm not entirely sure if that will force a change in which streaming server I use, I'll look into it an give it a try, see how I get on.

I've setup open DNS on the system I use to stream onto, testing now, so far so good, I'll need to test it longer to see if this has really resolved the issue, thanks for you help on this matter.

Unfortunately I still have the same issues, it's stopping to catch up but barely trying to use my connection.

I've confirmed it is definately using the new DNS servers, I'm going to try a few other open dns addresses see if I can force a change to a different streaming server.

I have the same issues as this, but with a 20MB/s connection which should be more than enough. 720p vids pretty much anytime I want to watch them, but even 480p in the evening's or shortly after the release of a popular series (E.g. Naruto). It is impossible for me to watch anything as it pauses every minute or so. I should note that I posted and did these tests in the middle of the day after giving up trying to watch Naruto in 720p.
