Videos from USB Player

Hi

I have handbrake tool to convert the videos to mp4 to play it in my Roku. All songs are in mp4 file format and also in different files. So I have to select each and every song to play it, I am not able to play it as a playlist.

1. Is there any way to create a play list to play it from USB Drive.
2. Can I use HandBrake tool to connect these different files into one list. OR Can I create a single file as mp4 using HandBrake?


Thanks
Ambrose
