I have Netflix, Love Film (Amazon Instant now) and WWE Network. I find Netflix to be totally flawless, I can be downloading on my PC and still Netflix works with a really decent picture, no buffering other than 3 seconds at the very start, perfect. With Amazon Instant the picture quality can be poor and it can often stutter or keep buffering every couple of minutes. With WWE Network the video can skip back a few seconds every so often. I am using all on a PS3. Also with Amazon or WWE I need to make sure I don't download much on my PC at the same time.

Any idea why ? What technology does Netflix use that is so good ? Does anyone else have the same situation as me ?

I personally don't have a problem with either, and Prime is being air played to my apple tv. I don't have a massive BB speed, under 8meg.

I see the opposite, not that I have problems with Netflix, as I can reach bitrates of 6400kbps (via PS4) for 1080p content.

However, Amazon Prime's best 1080p streams at a staggering 10,800kbps on my PS4 whether via the US version (streaming from America) or the UK version (much closer).

I never have buffering issues or any other problems.

Perhaps the software on your PS3 needs updating? (Is it on WiFi or Ethernet?)

I Had the exact same problem, Lovefilm buffering stuttering Netflix perfect, I only have Netflix now, Lovefilm couldn't solve the problem (there cs is terrible) I never did find a solution, I suspect Lovefilm have problems in parts of the UK but they don't want to admit to it, I'm on BT infinity 2 75mb down 18mb up so it's not my BB that's the problem.

I think it has something to do with the device you use. I used to use the wii and I had the same problem, Netflix was fine but lovefilm kept buffering. I now use my iPad or airplay to my Apple TV and I don't have any problems.

This is possibly true, although using the iPad to airplay to the ATV is probably not the best example.

Lovefilm on iOS is not HD, and at 1500kbps, the stream itself is not too difficult to get around without causing too many issues.

Other platforms though may have an HD stream, which for Amazon Instant Prime can reach a staggering bitrate of around 10,600kbps, which even for people with double that bandwidth, there can be bottlenecks.

The highest bitrate I have seen for 1080p HD streams on Netflix was around 6800kbps, but to be honest, the quality doesn't look worse than via Amazon on any TV I have viewed.

I don't get buffering issues myself anymore, but I did in the early days for Lovefilm.

My Wii is the original one which only does SD. Prehaps it's more do with the service improving over time though.

I've tried Lovefilm on numerous devices Xbox 360/PS3/Wii/Sony SMPN100B and a Digital Stream DPS-1000 with two different ISP's Be* with a download speed of 18mb and BT Infinity 2 with a download speed of 75mb and they all stuttered and buffered, For me Lovefilm is terrible and I would never go back, Netflix works perfect on my Roku LT and my PS3 and the Roku is wireless, so same hardware, same ISP, Netflix works Lovefilm didn't, its a mystery

Very strange! I use Amazon Prime (alongside Hulu+, Netflix & WWE Network) on numerous devices (using wifi) & all of em work perfectly! ... No buffering @ all!

How did you find out the bitrate if you was using amazon for the ps4, im thinking of signing up to amazon 30 day free trrial using the ps3 and bt infinity wireless.

I think one reason it works so well is because of Netflix's sophisticated use of CDNs (Content Delivery Networks). These essentially put local copies of content distributed around the internet so there's likely to be a copy near you - so the latency of the internet affects delivery less. The further the content is away from you (in network hops) the more likely the traffic to you is likely to get disrupted e..g by someone else's streaming traffic.

Netflix even designed their own hardware and shared it to encourage ISPs to play along with their design and make it suit their needs.

I'm sure Amazon also use CDNs (all content sites do these days - a wild generalisation but I think it's probably true!) but perhaps not so extensively as Netflix.
