I need a tool to use Mostly backup to hard disk storage so I don't scratch originals or have to hunt for disks to watch. I have searched it on google and found a guide blu ray to mp4 with multiple soft subtitles, With no doubt, I tried Pavtube Bytecopy and it can achieve this goal, I prefer mp4 format, started looking for mp4 layout. there may be a reason no one processes pgs subtitles to mp4. looking for a way to extract pgs subtitles and add to existing mp4 file. media player classic - home cinema doesn't seem to care about what's in a file. the only reason for mp4 over mkv is smaller file, some 1-2gb vs 4-7gb for 30 min episode. In fact, the pavtube Bytecopy are better control over multiple audio and subtitle ripping.

I have none others devices, but they told me It can also support transfer DVD/BD discs to my all device, such as Samsung, Apple, Sony with smartphones and tablets.

I think maybe wouldn't be a sticker for file format rules or at least maybe a matrix to popular players and formats or maybe more customization for processing input and output.
