ok i dunno how ppl convert huge avi/mkv/mp4 files to rmvbs.
i have been trying everything that i can get my hands on, but they completely ruin the quality of the file. the quality gets worse AND the size is still around 100 MBs.

i really dont know how to convert the files without damaging the quality..

i have downloaded .mkv or .rmvb files, the size around 50~70MBs and the quality is excellent! how do they do it? help!!

i cant even find something that can trim the video (.avi/mp4/mkv) without changing the quality! what can i do?
