That they don't work in the techroom either indicates that it's not a basic code issue, if other movies in the techroom do work. And they do work fine for me btw, in the techroom at least. I haven't tried end-of-campaign testing yet.
There are only three cases that it should give you the "Unable to play..." message: 1) You are running the standalone server and not an actual game, 2) You are running with -nomovies, 3) The movie can not be found on the disk. I suspect it's number 3. Make sure that you have the filenames correct, endprt2a.avi and endprt2b.avi, with no "a". Make sure that cutscenes.tbl hasn't been modified and that all of the movies are in the same folder. Also try moving the movies to the root game directory and see if it does anything different.
Well, they show up in the techroom, they just don't play. FS says "unable to play movie..."
as to the three cases you mentioned:
1) I am not running a standalone server, I'm playing single player campaign. This would affect other movies throughout the campaign, which it has not. All other movies work just fine.
2.) I verified my launcher6.ini file and the checkboxes in the launcher to insure that no hanky-panky was occuring and -nomovies is not present anywhere, so it's not an accidental flag. Again this would cause no movies to play. The rest play fine.
3.) I have my movies in my mod mediavps/data/movies folder. All movies are present and accounted for...
AH HA! The downloaded movies are named endp
art2a.avi. Note that I downloaded these from the karajorma's faq link and directly unpacked them to their present location. If anyone else has this problem, they probably have the same misnamed files from the compressed download that I have.
I must have read your post 6 times before my brain stopped automatically adding the 'a' to the filename you wrote. It didn't sink in until I chacked the cutscene.tbl file and saw the vowel deficient name there.
