I bought Sony Vaio PCG-GRT77/B, earlier there was Japanees windows XP
home edition. I tried to install XP Pro SP2. I installed drivers of
PCG-GRT260G cause they were in English, Every thing worked fine except.

1- USB ports they are working at low speed.
2- The tv Tuner Card, when i installed giga pocket ver 5, there is a
dll error.

Can sombody give me a solution or link, also does the tv card support
PAL system.

Manager, reboot and see if the "enhanced" controller for USB2 is then

Gigapocket seems to be difficult on many Vaio laptops.  Try posting in
