Just to help,
Ive tried
- Different versions of Vista INCLUDING 64 bit
- Different MPEG-2
- Turned services on and off
- Different Video card
- Vista WDM driver Vs Ati latest catalyst driver
- Vista WDM driver Vs Latest Fusion Driver (FYI WDM one was actually better)
- Faster HDD
- PCI BIOS Settings
- Ram timings
- BEFORE installing ICe after ice
It all comes back to the driver.
