This makes no sense. The data rates of HDTV tuner cards are quite small, in the range of 19 megabits, a fraction of what any ethernet card or disk controller or many other cards do. There is no reason for what you describe. Playing back hi-res video on the other hand does take a lot of data movement, about 500 megabytes/second, which is why only AGP cards (or pci express) really can cut it in that department.
