My first shot for help is in the NERO Forum possibly because something has changed in NERO. I am on the latest version of NERO 6. Up through the summer of 06 I could burn home made .wmv files onto a DVD using NERO & they would play fine in WMP . I could give that DVD to anyone who had WMP on their desktop and they could play it. It also played on all my home DVD players. This was prior to upgrading my NERO 6 to latest patches in the fall of 06 Now - the only way I can or anyone can view a NERO compiled DVD is either with NERO or with VLC. (& yes I was using the same media types - however, since then I have had to play around with alot of different media just to get a DVD that plays in the standalone DVD players at my home - the ones I used before don't play now - another curiousity since NERO is the only major software change I think I have made other than MS SP's) I have gone back and checked the old nero DVDs & as of today they can still play in WMP - but the ones I have compiled since Fall 06 do not play in WMP? I can get them to run properly in VLC and on some of my tv players. The issue is this - when making copies for family members(like Mom) who are on a Windows platfrom and are not that PC literate - -it was ok to just send them to them because I knew that they would play in WMP if not their tv player. I have read that WMP cannot handle MPEG2 - but then why did WMP play the nero burned DVD's for over a year - was there something in the NERO upgrade that changed the way NERO does a compile and disables the capability to play in WMP? Ask me anything - I am stumped. If you think there is another forum room I should post this in to get help - let me know...... I really appreciate any input here. P.S. Here may/ may not be another set clues in helping to trouble shoot this....: (1) When a friend took my NERO DVD and duplicated copies for me on her DVD duplicating machine at home and returned them to me - curious - but now I WAS able to view them in WMP (2) I create those .wmv files in MS Photostory 3 first. I used to be able to view my Photostory .wmv file inside of the Photostory viewer - but during this same time period - Photostory viewer stopped working for me as well - - so the only way for me to view my new .wmv files was to go out of PS3 and view them in WMP or VLC.
