First of all thanks to all at PTVUPGRADE,DVRplayground. This is great Stuff!My setup:Tivo1: DirectTivo: Dual drive(40gig/120gig) upgraded with PTVUPGRADE utilitiesTivo2: DirectTivo: Single 400gig drive built with PTVupgrade.Windows XP Professional system, latest updatesNetwork: All Wired. Recommended DLINK 10/100 usb adapters on the Tivos. Older SMC Router(Don't think this matters since everything is wired). I have entered MAC addresses in the router to create static IPsWhat works:Telnet, FTP, TivoWeb, MRV,video extraction, video streaming to PCWhat does NOT work:HMO - this worked and then stopped working on both Tivos. Worked for a few days then stopped. Entering the IP address of the PC running Tivo Desktop into the Tivo does not help.What is intermittent (in case it matters)?TivoWeb viewing Now Showing List(Some times does not complete) I figured this was because of the long lists of shows on the tivosStreaming has occasionally stopped for no reason; I can stream again with no problem.What I have done:Tried disabling Windows firewall & Mcaffe - no changeReinstalls of Tivo 2.3 Desktop do not make any difference, I also did a registry clean after removing Tivo desktopLooked at ports opened in Firewall, appear to be OK but I did not do a complete inspection, I see a number of ports opened for Tivo.Tivo Desktop 2.3 does see the 2 Tivos on the networkI have seen some references on the Tivo support website, but they all seem to apply to a Mac systemsThis appears to be an issue with the Tivo desktop software or something on my PC any suggestions? Thanks for any help!
