I have a DMR-E80H that is about 3 years old and was running fine with the original firmware. I put in a new 8X DVD-R and it said it was incompatible. After researching the forums, I decided upgrading the firmware with the latest was what I should do. Big mistake. It worked fine the first time with the 8X DVD-R. But now, it will only read about half of the old DVD-R's that it created using the original firmware. And it also has a lot of problems with the new 8X DVD-R's. I have to restart it (unplug, wait, etc.) several times and sometimes it will be able to write to the disk. I have also reset to the original factory settings a couple of times to no avail. Is there any way to fix this? Can I go back to the original firmware? Is the machine basically a TIVO now? Please help!
