As the subject says I'm trying to merge about 13 different 1-2min scenes from multiple Blu-rays into one file (approx 15min)... I have the seperate files of the scenes I want, but I have no clue how to merge them all together... Mostly due to them all having different HD audio tracks,  some are Dolby Digital HD and some dts MA, and all are 1080p 4:3...

I want a app (Windows or Mac) to let me transcode the audio tracks to the same format, and then merge all the video files into one piece... While still keeping the Audio lossless 5.1 and the Video lossless 1080p.

Is this at all possible? Googleing has just showed me generic video converters... Also I don't mind paying for software

Thanks for any help! =D
