View Full Version : Amazon Unbox Very Slow - Is There A Problem?

I find that downloads like Amazon Unbox (recently made quite obvious with the pilots NBC put up) and other video downloads (like The Onion) seem to take way longer than I think they should on my TiVo. I've seen my connection (cable) at over 500KBps (yes, B). I know not everything is the same speed but...

So it seems to have taken nearly a day or so (lets guess 18 hours) for each of the 1 hour (well, actually 42 min) pilots. Based on a 1 gig file (about the right size, IIRC) that comes out to about 15KBps. It took 3 days of basically non-stop downloading to get the 4 pilots that I downloaded.

Does anyone know about how fast things download for them in Unbox and such? Can someone think of a way I can find out what is going on and if there is anything I can do to improve this? I don't know enough about network monitoring to know what to do (I'd use WireShark but I know that is the wrong tool).

The base causing this question is when I first got my S3 (shortly after they were released) I had a ton of trouble getting it to use my home network (wired Ethernet). That problem went away after a while (I don't get messages about it, things seem to work). I believe a software updated fixed it, but I always have this little nagging worry about it and the slow download speed on video makes me wonder if it is having problems.

I don't expect 500KBps, but most sites seem to give at least 50KBps.

For Unbox, does anyone know if TiVo connects to the normal servers (like a PC would) or if it goes to a special TiVo server? In other words if I downloaded a show on my PC would that speed be comparable to what I should get on my TiVo (something I haven't tried)?

I had the same experience with my first Unbox download. I contacted my ISP and they had me reset my modem. The speed went up dramatically. I don't know whether this is your problem or not.

Why not go to http://www.speedtest.net/ and test your connection speed. If it is slow, reset your modem and test again. If its still slow call your ISP and ask why you aren't getting what you are paying for.

While the speed did not approach my testing speed of ~6Mbps download speed. They all come in at close to 1hr each or around 2.1Mbps download rate.

All mine download in 10 to 15 minutes for the NBC pilots.

Weird. That's more along the lines of what I would expect. I wonder if something fishy is going on. I'll have to investigate further tonight when I'm home.

Aaron,

Out of curiosity:

What time and day did you download them?
What's your Broadband Source and Speed?

There was a number of complaints that it was taking 2-3hrs to download the day after they became available on Amazon. I think the system was being overloaded with requests.

I think mine downloaded quickly but I can't say that I watched them.

But I did download a movie from Unbox 2 weeks ago and it was almost a 2hr movie, it took like 5 hours to download.

I only have DSL rated for 1.5Mbps max, but I am wireless from my modem to the Tivo. Just seem that it shouldn't take that long to download that movie.

That's what I though. Like I said, I had some issues with the network when I first got the box so I'm rather suspicious of it.

I've been downloading Unbox content at the rate of 30 minutes per hour of recording.

I have a 30mbs connection. I downloaded them in the evening.

See, this is kind of what I was worried about. Does anyone have a good idea of a way to see what is going on?

It's downloading slower this evening. I'm downloading the Life pilot and after 3 minutes it's only showing 6 minutes of the show has downloaded. At that rate it will take around 22 minutes to download the 44 minute pilot.

I am downloading to two TiVoHD boxes concurrently so maybe that is slowing it down for me.

I downloaded Bionic Woman again last night (~9:20pm CST) and it was 23mins to download (5.6Mbps - fairly close to peaking out on my Cable Modem Service which tests at ~6Mbps)

I think a lot depends on the traffic on Amazon Unbox and then it's limited by your broadband connection, which I would have to assume had a lot more traffic than normal when they first released the free pilot episodes.

I agree, but this isn't the first time this has happened. I notice the same thing on the only TiVo Cast I subscribe to: The Onion. While the episodes are only 2 or 3 minutes long they take quite a while to download also.

I've got to figure out a way to monitor what's going on.

From the time you first select to Download how long is it taking for your Now Playing List to show the title (with blue recording icon) - does it show up immediately or does it need to network connect first in order to know it should start Downloading?

Mine usually starts in 5 minutes. Sometimes it can take a few minutes longer for mine to start.

It would show up pretty fast, it just takes forever to complete.

I sniffed it last night while it did a standard connect, and I didn't see anything that stood out like lots of retransmits.

I'll have to see what it does when it downloads a program, to see if things are the same. Maybe this is just a slow connection between my local Comcast and the servers for video downloads.

While you may have excellent speed over your cablemodem, it sounds to me like Amazon may be having troubles with bad routes to some of their CDN distribution nodes, causing poor transfer performance to *some* customers. I personally get decent performance when downloading shows via Unbox (sub-1-hour for the NBC pilots on Unbox). Unfortunately I'm not sure, without suggesting the use of some packet-sniffing tools, how to determine what IP to try diagnostic measures on, as the IPs will likely vary widely depending on the node you're hitting from your specific location.

Maybe I wasn't being patient enough (to wait for one of the '...4 attempts that occur an hour to synch') but after forcing the connection I saw that the download showed up in my NPL.

The 45 minute program took about 25 minutes to complete download.

I see the same thing - unbox speed is horrible. I can download to my home PC wireless or wired at 1.5Mbps. In almost 7 hours of downloading Letters from Iwo Jima - only 1hr 5 minutes of video had been downloaded. This is my first try. I am not impressed.

I just download the original House on Haunted Hill this morning from unbox. The movie is 1 hour 26 minutes long. It took 25 minutes to download it.
