Proposed Handbrake improvement.

I've been busy ripping DVDs from my collection and I've run into an improvement for handbrake.

While converting TV episodes on DVD, I wanted to autoname the new file using output pattern S01-E0{title+offset}  like {title+5} for disc 2 in a DVD set where the title-1 is episode 6.

Handbrake - HandBrake is an open-source, GPL-licensed, multiplatform, multithreaded video transcoder, available for MacOS X, Linux and Windows

So I downloaded the codebase and found where in Windows code tree auto naming occurs.  HandBrakeCS its in Main.cs and Handbreake WPF autoNameHelper.cs

I have this code compiled and working locally great!

Now a commentary:

Dear SourceForge:

You have to be kidding! Separate logins for main site and forums site.  What is going on?
SourceForge also give lip service only to OpenID.  I initially created my user account with OpenID and  only to find I have limited permissions and I would need to create 'real' account to do anything useful.

SourceForge your site is terrible and I would recommend handbrake moving to another open source hosting site.

destinationFilename = UserSettingService.GetUserSetting<string>(UserSettingConstants.AutoNameFormat);

                    //Add ability to auto name file using {title-offset} or {title+offset}
                    // example {title-1} or {title+3]
                    // This is extremely useful when ripping DVD of tv show episodes.
                    #region AutoName based on {title-offset} or {title+offset}
