    Another TiVo user prompted me privately to check my DNS which was configured to my default ISP (Bright House Networks). Using GRC's fanatastic DNS Benchmark Freeware tool, I discovered that my default DNS was unreliable. I reconfigured my DIR-655 router to use Sunbelt Software's DNS and voila, my Premiere user interface (HDUI) speed had a tremendous improvement. My waits for filling in program information when navigating My Shows improved significantly.

    GRC's Freeware DNS Benchmark download page --> http://www.grc.com/dns/benchmark.htm

    Below is a snapshot of my DNS Benchmark results. I encourage you'll to give it a shot. You'll see that Sunbelt Software was one of only a few DNS' providers that had all green results running the Benchmark.

    Yes changing the DNS address can make a big difference with the streaming services.
    Although for most people it's probably easiest just to use the DNS Ips from either Open DNS or Google. i used to test mine every few weeks and change them to the fastest ones. but now I just use the Google DNS Ip addresses. i can't use OpenDNS because it blocks me from accessing one of my domains for some reason.

    Using a third party DNS can actually slow your streaming services.

    Or live on the east coast and use a west coast DNS.

    OpenDNS and Google's DNS have gotten quite good at geolocation over the last few years. So it shouldn't be much of an issue anymore using those services.

    Very true. For example, I used to have major problems with YouTube when using OpenDNS. This hasn't been a problem at all for me in quite a while.

    I'm on Day 3 of using my new DNS configuration. I'm still shocked at how much faster my TiVo Premiere and Premiere Elite/XL4 are in populating show data. Its radically different. One of these days I'll create a video to demonstrate the improvement.

    hmm, I had to do that for my PC because of the slow ATT default to google, good point about changing it for TiVo too.

    You should just need to change it on the router.

    what sort of speeds are people getting for "good" servers?

    basically my ISP's (comcast) servers look "OK" to meusing the gibson tool, but seems level 3's are a little bit better.

    Poling around on the net there's all these other snippets that it's best to just use your ISP. So I figure if comcast is "good enough" I might as well just use it.

    Also in another thread someone mentioned that their router is caching so it's best to use your router in that case rather than pass the DNS server addresses along. How do I tell if my router is caching? (I think it's not since it's slower then the DNS server its supposed to be using according to the gibson tool)

    also- when there's 2 dns servers- is the second only a fallback if the first falls?

    If the DNS requests when using your router come back in no more than a few milliseconds, then it's caching. For me, the test came back and said my current DNS server, which is my router, was much faster at responding to requests than any other server. Since the test gives more weight to caching results, my router was listed as the best DNS server.

    I don't think my router does any DNS caching of its own (DLINK DIR-825 with stock firmware) - I have it setup as a relay such that it acts as DNS server on my LAN but just relays requests to the configured DNS IPs.
    I doubt TiVo units do any DNS caching on their own so all requests are forwarded to DNS servers. Router DNS caching certainly sounds like it would help given the large number of DNS requests the HDUI makes.

    I guess as an alternative to custom firmware one could setup your own DNS server on the LAN assuming you are OK with running a server 24/7. I tried my best to stick to HDUI for several weeks after DNS optimization but eventually went back to SDUI again as it's still so much faster and has less bugs/annoyances, so now I don't really care about DNS much optimization as SDUI doesn't need it.

    too much effort- lol.

    But seriously I would but currently im using a actiontec moca router and the open source things dont work with the moca which is the reason I'm using the router in the first place.

    can a 'human' set up a dns server themselves?

    If a 'human' can figure out how to run a Linux box, then yes. ;)

    sorry no luck there.

    lol.

    I do have a windows home server though...

    I think my best bet is just to try and figure out how to have my router pass along the address of a good DNS server instead of just telling everything to use 192.16.1.1

    My NetGear router's "Basic Settings" has an option to use the ISP's DNS servers, or specific ones. It still passes itself to DHCP clients, but uses the specified servers for resolution.

    I changed it from Google DNS to Time Warner's a while back, with impressive improvement. (Turns out that Google DNS performs very poorly in my area.) Then I ran DNSBench and switched again to OpenDNS.

    I need to run additional tests to see if the in-home systems see a significant difference between resolving to the router's DNS or directly to OpenDNS.
