It is Dell Precision M4800 64 bit with Nvidia Quadro K2100M graphic card. Since I've installed Jessie last year I have nothing but problems with VLC:
1. I can play DVDs but the screen is flickering awfully. Useless at worse, can play some after a lot of preferences tweaking at best. 2. I have a number of movies/videos in MP4, some in AVI format. Some of MP4 play nicely but most of them and neither of AVI files do not play at all. Usually the sound track is there but no video at all. Attempting to play some of them actually hangs up the system and reboot is required. For now I found a solution by installing SMPlayer. It plays everything above without any problems. I however would still prefer using VLC, to which I simply get used in past years. Tried to follow this WIKI https://wiki.debian.org/ MultimediaCodecs#Available_Codecs_for_Debian after installation. I would prefer to avoid not recomended deb-multimedia.org. Any advise, please?
