I have repeatedly asked Tivo tech support "What is the expected LAN speed capability on the premiere" and they don't know. I have the same question posted to TiVo engineering on a escalated case number and weeks after posting I'm still waiting. TiVo Weaknees tech personnel say it should be capable of 100mbs however I have never seen transfer speeds over 65mbs. Usually its very erratic and much slower. When looking at: TiVo Settings/Network/Network diagnostics/Transfer history/ I see that all 3 of my Premiere's perform with the same very erratic LAN speed. My questions to the community is: What do you see? and is this why the streaming capability of the Premier is so plagued with issues? FYI: My Cat 5 TiVo LAN network is fully tested using PC's and OOKLA speed test, my results are a sold 120mbps both up & down and all my boxes pass the extended hard drive test.
