Here's a question...what format are the VOD files in...MPEG2 or MPEG4? You'd think since the HR20 can do MPEG4, that they'd utilize it to save bandwidth...
1 - HR20-100S
1 - HR21-100B
1 - HR22-700
1 - HR24-500
1 - R22

I did try something again last night and it was a bit better, but I think too that we will be subject to server loads at peak times from Directv. The only time I've tried was around 9 or 10 PM eastern.


Unlikely it will be from the Directv end, who is actually using Limelight Networks to store and distribute the content. (provide services to Amazon Unbox, Netflix, Microsoft (Xbox), Sony (PS3)

R15-500 connected to an old Sanyo (1 line)

cougar,

use this site to test what you are truly getting to your dsl modem:

http://www.speakeasy.net/speedtest/

as for download times, report back what you really get after a good test. i had one jack in my house without a dsl filter causing too much noise. i'm now up to a consistent 5 mbs for the first time.


I'll test it when I get home tonight. I did a speed test on another site a few weeks ago and I was getting better than 5.0, I don't remember the exact number. I need to do another test because I moved to another jack since that test. Thanks for the link :)

Here is another site with more servers to check: http://www.speedtest.net/

Also remember that while you may get a good test from these sites, that VOD is a much larger download and may have problems with your ISP. My ISP is upgrading their system for their own VOD roll out.
Both of these sites show I have my "full speed", yet VOD doesn't always come at that speed [almost never] and the last time I used it, it popped up with the message telling me there was a problem with my internet connection, about 10 min into the download. I selected fix later and it continued without further problem.

I have only downloaded one movie. It took me roughly 2 hours to download a 2 hour movie. I have a wireless bridge connected to my HR20 (the Buffalo WLI-TX4-G54HP) and my router connected to my PC is the Buffalo WHR-HP-G54. Both of these are 802.11G with MIMO performance (not sure if that really helps or not). I also have DSL with a download speed of 2.5 to 2.6 mb according to the speed tests that someone posted a link to. As I was downloading the movie, I was able to start watching it after a few minutes. Just wish they had some high def content though.

I noticed this issue too. It seems the download speeds just aren't up to par with it being "on demand". We tried viewing the movie "Open Season", last weekend. I started the download and even waited about 5 minutes. We started viewing the movie and within about 25-30 minutes, the movie stopped and we had
"caught up" to the point of download.

I have a 10mbps download speed and I know it was working at about that, at the time(I used the same speakeasy site mentioned in this thread).

You must have a "choke point" somewhere in your ISP. If I can get my "3 Mb/s", 30 min buffer would have worked. My last d/l was in the middle of the night [with my error message] and came through at 1:1, by the info shown [1:55 show that started & stopped in 1:55]. FWIW

Now I'm getting better than 6.0 from speakeasy and speedtest.net. I didn't know that was possible from an "up to" 6.0 DSL package! :eek2:

I'm okay with my DOD download speeds, it seems the people who download faster usually have cable broadband connections. :)

Well with a 7.2mbps DSL line I can start watching a program after seconds. I don't wait for the whole program to download so I don't know how long that would take.

Unfortunately I only get about 1.5M/s down and it's pretty frustrating. Waiting 50%+ for something to finish before viewing not my cup of tea. Can anyone confirm the format that these movies are in? If they aren't mpeg-4 I think they should do some converting. That might help quite a bit.

Not to mention reducing file sizes is friendly for the internet environment. There's only so much bandwidth out there.:grin:

This morning I'm getting a pathetic 800kbps download on DoD. I ran a speedtest WHILE I AM DOWNLOADING and this is what I got..

So it is definitely not my internet connection.

"Definitely"?
It still could be your ISP connecting to D*. Clearly the video is being choked while a local server "burst" isn't.

That's not a local burst. In any event, I have the DoD download going and also a ReplayTV receive going now. The ReplayTV receive is getting 1.2mb/s and the DTV download is still getting 800kb/s. :(

I just ran another speedtest and got the following from a Los Angeles server to rule out the "local burst" theory.

Posted Image

3.6mb/s down with me already using 2mb/s, so I'll still say...it's definitely not my ISP - locally at least.

It appears that DTV is using Limelight Networks for their video hosting. My firewall traffic logs show http requests from the HR20 to 69.28.159.141, which RDNS'es to rdcds4.iad.llnw.net which I think may be a "Content Distribution Server". Perhaps IAD is Washington, DC?

Acceptible latency to them. I wish I had a way to do a reverse traceroute FROM them.

Speedtest to Washington, DC is great...

I really wish I could figure out what the secret to multi-mb/sec downloads is. It look over an hour to download a family guy episode. :(

Well please post it if you ever do find out.
I have my ISP's western regional network guru trying to figure it out.
I have only a 3 Mb/s connection and my HR-20 seems to pull only 1.5 Mb/s.

What happens if you d/l in the middle of the night?

I'm doing SNMP and Netflow traffic monitoring on the switch port that the HR20 is connected to. I use a unix box primarily but you can download PRTG for Windows if you have a router or switch that supports SNMP.

So the question remains for an expert on the forum or a D* employee familiar with the situation:

Is DirecTV (or LimeLight) screwing around with download speeds?

I wonder if in my case Global Crossing could be the culprit. It appears that LimeLight has a node in Atlanta (ve5.fr4.atl1.llnw.net. It appears to hand off from LimeLight to Global Crossing and finally to Comcast.

I have noticed that with a new router the download speed is quicker after Comcast fixed my RG6. I had a tree branch fall on it and it knocked it out of place, so I was getting intermittent Internet on my computer. They came out today, and I also bought the new router today (Linksys WRT54GS) and it seems to be fine. I downloaded three programs. On one program it stopped just before the commercial, but I don't care about that. I don't believe Comcast is conspiring to sabotage my signal with DirecTV via Internet, they don't know what I am downloading.

Thanks to the collective knowledge of this group my DOD is installed and working properly. Using DSL the download speed is painfully slow. It seems the only practical thing to do is to download at night. Not really "on demand" but OK. I assume the HD downloads, when available, will be even slower. Anyone using a cable modem? How is the download speed?


My download testing was fairly OK. It was not super fast, but also not super slow. What is your DSL speed?
