I seem to have broken my Arcsoft Totalmedia installation. The player opens up and all menus *seem* to work, but it will not play either regular or HD-DVDs, and it will not play them directly from DVD (says insert a valid disk when I try) or from file folders – (just sits there and does nothing). It will however play regular media files and it will even play raw EVO files if I drag and drop them directly onto the player. I have tried uninstalling and re-installing several times to no avail. I suspect that I broke it when I used PowerTools to remove the Japanese trial and clean the registry and delete old Arcsoft stuff, but I am not sure. BTW – PowerDVD is working just fine. But, I rather like Arcsoft – the picture and the especially the sound are much better.
Any thoughts or suggestions short of re-installing Windows Vista? I did do a restore from an earlier point, but am really reluctant to do a full Vista reinstall - for a number of reasons, but I am at my wits end. Arcsoft, of course, has been no help. Thanks for any and all ideas.
