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.
