I can't for the life of me figure out what is going on, the problem started a month or so ago. No changes have been made. Streaming videos (via Hulu, TLC etc) is just fine on my iPad and other desktops / laptops in the house, there's just something with the HTPC that isn't working right. I've tried everything I could think of. Spyware and rootkit scans reveal nothing, as do virus scans. Windows is up to date (Windows 7), Flash player is current. I use Chrome for streaming, things get marginally better in IE. I've uninstalled / reinstalled Chrome. Firefox is no better. I have 20Mb Comcast, and consistently get those or faster speeds. Help! Thanks in advance!
