Of course there is little to beat JRMC when it comes to music but it's not considered to be the best application for DVD and Video. I use it for a few AVI files so not enough to give you constructive feedback. Maybe interact is the best place to ask that.
What I would say is that most people, when setting things up in the first place, tend to opt for a 'simple set up' and avoid apps like Girder. Then, when their simple set up is working nicely and they know how it all hangs together, they are ready to ditch it in favour of something that does everything they need in the best way possible. That's why people use Girder and DVD players like Zoom player. My advice to you is to think longer term and accept the fact that a simple set up will not seem quite so attractive once you get going. Girder, for example seems a bit daunting at first but I found that it was days rather than weeks for me to feel that I could comfortably find my way around and make it do what I want so well worth the initial effort. Months later you find that you can do really powerful stuff. Anyone who's used Girder would never be without it.
