My Phllips DVD Recorder/Player normally plays everything easily and plays many formats from Video (standard DVD format) to DivX, Mpeg4, MOV, AVI and so on. I have been trying to play disks I made on my Windows 8 laptop and keep getting the error message "playback feature may not be available on this disk." n I know it isn't the brand of disc as I have used the Verbatim to make standard DVD format recordings on another DVD-R/player I have and played those fine on the Phillips. All my previously recorded DivX file discs play fine (I have hundreds of them. I have not had this problem before. I tried UDF and Joliet System structures. I used my Roxio software, my Divx software and my AVS software and got the same error message. Is it the Windows 8? I did the other hundreds on my Windows 7 machine but the DVD drive died on that one, probably from overuse. :-) Can anyone give me some advice on this issue? I don't normally have problems like this and do a lot of videos in AVI and DivX where I can get 40-60 video files on one 4.3G disc and sometimes more if I reduce the resolution because the DVD-R and TV fill in but this time I have tried everything up to 1080p from 320x140.
