I'm one of many who can't get their 5005 to upgrade the firmware even though Liteons instructions are followed precisely. If you're aware of this subject, you'll know that probably half or more of 5005 owners have run into this "wall". In fact, in my case, Liteon Tech support has offered to take the thing back since I'm not pleased with their inablity to provide answers or a fix for it. My question is, does anyone know how some owners are getting upgrades to install while others can't? Is it a batch problem or what? Frankly, with the exception of this upgrade issue, I really like the 5005 very much. It offers a great many features not available on much more expensive machines & (for me at least) has been very reliable & user friendly to operate. I want to get upgrades to install mainly for the 3 hour recording feature which is apparently available on some firmware versions.
