I am new to this site, but I had to register and let others know that I also have had for months a myriad of issues relating to the Giga Pocket Hardware Application Overlay nightmare. FINALLY, after numerous hours of restoring from the System Disks and endless searchings on the web, I have found that if you reinstall your drivers for the Sony Mpeg2 Encoder Board in System Properties it removed that issue. At least it did for me! I probably could have found the answer IF I could read Japanese
My system is Sony Vaio p4 1.7 GHz 80GB HD WinME
I hope this can help/work for others experiencing this nightmare - God knows I needed it months ago.
