I just got this unit for Christmas, mainly as a vcr replacement, and so far have sucessfully recorded onto both dvd+r and dvd-r when using the quick start recording. I've also recorded successfully when setting the timer with dvd+r. However, when I try to use the timer with dvd-r (I'm using Tdk 4x media)the unit will freeze with a blinking "stop" on the front display. I usually have to uplug to get it to eject the media. The timer display shows "fail" in the status column. I haven't yet tried to update the firmware. I downloaded the firmware from the Liteon site, and the date stamp on the file in the rar archive is 10/27/04. Since I purchased this unit in December, I'm thinking it may already have the latest firmware. Is there a way to tell which version of the firmware the unit currently has? In any event, I'm not sure that updating the firmware would help with this issue. I plan to try a timer recording with Sony dvd-r media later, to see if that makes any difference. Any feedback would be appreciated.
