Yup. Sitting here in a rural area of western Montana (redundant? 
), my access to the web is via comparatively slow DSL. Most of my GT time and all of my GT lesson streaming is on a nine year old desktop with 8 GB memory (2.8 GHz). And there is [u]never[/u] any buffering.
Try searching the GT forum for related posts involving similar gear and setup as yours.
Most of all... contact GT Support. Click on "Contact Us" found at the bottom of every (I think) GT page.
Good luck.
