Philips DVDR985 Progressive-Scan DVD Recorder and Player
Would not reccomend, but if you have one then here is a fix!
This product gave me many problems from the get go.  The good news is that you can upgrade the firmware with the newest available software and it will fix all associated problems.  It will eliminate the disc errors and also provide support for DVD+R.  There is an earlier version that claimed to do this but it did not work but the newest version does.  (...)  I know it seems like a lot of work but if you are already stuck with this unit then it might as well work like it is supposed to.
