Hey, iv'e been wanting to convert all my anime so that i could watch it on a normal dvd player, but im having trouble getting to that format because of all the wierd formats anime tends to be like ogg, mkv and such. Anyone have any suggestions on a decent program i could use, without losing quality? Thanks.
