I'm new to BigPipe and new to AppleTV so I don't have a lot to go on here, but I've found renting a movie very slow. We rented a movie (admittedly in HD) last night and it took about 15 minutes before we could start watching the movie while the AppleTV buffered. My only other experience with AppleTV has been at a friends and they didn't have this... with ADSL. I'm on Fibre so I expected better.
I saw a post on here were someone else had issues and DNS was part of the issue. I've been using OpenDNS so I changed back to the BigPipe DNS servers thinking CDN optimisation might be the issue - that made things worse. The initial estimate I had was 55 minutes till the movie could start, on BigPipe's DNS servers it was 3 hours - I didn't think either of these options was acceptable.
I have a support call raised with BigPipe but we're still working through the "can you run a speed test" steps at this stage - which look fine. Just wondering, does anyone else have issues with AppleTV Movies, Netflix is flawless? Are my expectations wrong?
