I have some movies that have the audio and video set at 25 FPS. I use Ripbot264 to convert the video to 23.976, but my audio is out of sync because it was encoded for a video at 25 FPS. So how can I slow the audio down a bit to sync with the 23.976? Can I demux the two files and run the audio through something? Can the audio fix be done with a program? I read somewhere that a little program called besweet can be used, but it is a command you run at dos prompt. I have used things similar to convert audio from DTS to AC3, but I would rather do it somehow with a GUI. Any suggestions would be appreciated. Knox
Since I don't know what type of video (or audio) is involved, I can only generalize. Since the audio has to be stretched to fit the video, this .mp4 file was loaded into AviDemux. The Video is set to 'Copy' and the output 'MP4'. The audio (in this case it's .aac) is stretched using the 'PAL to Film' filter. Click on the 'Save' logo and give the new file a name (include the extension) e.g. newfile.mp4 http://www.afterdawn.com/software/video_software/video_tools/avidemux.cfm

Not sure about avidemux, I have used eac3to with great results a couple of times. It is command prompt though. Work with the raw audio file itself, demux using tsMuxeR or eac3to... eac3to will also remove dialnorm if present (which is a good thing). folder\eac3to.exe sourcefile.ac3 destfile.ac3 -25.000 -changeTo23.976
@odin24 Sounds like the solution. What do you use to play .m2ts files (I only have downloaded samples and while I can demux them, I cannot get any video playback). Is Tsmuxer used to mux the files?
Cyberlink PowerDVD plays the .m2ts files on a PC or Media Player Classic is what I use on the PC. My movie bank is formatted to .m2ts to play over the hard wired network on the PS3. I use .m2ts because a lot of .mkv files are already at a video level of 4.1 and ac3 audio. With TSMuxer, I simply run it through that and output as a .m2ts and it's ready for the ps3. Really, the .m2ts is just a container. If the audio is DTS and if the video is an odd resolution, I run the .mkv files through MKV2VOB and output at a .m2ts file. That program works every time. My intent is to have the my movis on NAS hardwired in my house. I have 1TB for backup, and getting close to 2.5 TB's of movies now. Another 1TB is being added for movie storage. Knox
I normally use my PS3 for playback (in Blu-ray format), external HDD or BD-RE. However I use MPC-HC with CCCP, FFDShow, and Haali Media splitter for testing on my PC... I do a lot of recoding. I believe all three are bundled in the CCCP package. The OPs solution is an excellent one as well (home network)... not sure about mkv2vob though.
I updated Haali Media Splitter and I can get playback in MPC - but the video is too jerky - maybe my PC is too slow.
