Gigabyte MA770T-UDP3 motherboard
Phenom II X2 550 Processor
2GB DDR3 RAM
Hauppauge Nova T500 HD
Windows XP Professional
Bog-standard DSE freeview ariel with clear view of Mt Fitzherbert transmitter
Panasonic 42" HD-Ready Plasma TV
I have near-perfect reception of TV1 and TV2, 3 is watchable but is a bit jittery. Prime is very jittery and will hang occasionally.
Can anyone suggest any steps to troubleshoot this poor performance?
Thanks in advance
