I'm totally newbie so have patience please?
Sony BDP-S5100


Wow, exciting to have found mezzmo - to be able to browse my movies via my Sony DVD player.
I'm having fun but I thought that mezzmo can stream the .iso files. I tried to play one but it didn't work "There is no playable file." So I thought I would transcode it to MKV using the pre transcode feature.

I ripped the DVD using DVDFab 8. I rip only the main movie, not the entire DVD.

1. I wanted to pre transcode my .iso movie. I selected the one and the choice was to add it to the pre transcode list, so I did that. Then it asks which device so I picked my Sony DVD player. I chose to transcode to MKV. But surprisingly Mezzmo added lots of files to the list, none of them with .iso extensions but with .avi, .mp4, .mkv, and others.
What I was expecting is that one single .iso file to be pre transcoded. Did I make some silly mistake?

2. Does pre transcoding make a new different file and then delete the original? If so, I don't want my original .iso files to be deleted.
