Hello all. I've been using Mezzmo for almost a year now and I've still got a few questions about some of the features. First off, here is my system set up.

Z68 Motherboard
i7 2600K processor
8gb 1600 RAM
7200rpm Sata 3 HDD
Gigabit Network Adapter
Gigabit Router
Samsung TV UN40D6420

I watch a lot of anime and I download the fansubs that come out. These are mostly mkv files some dual audio almost all with multiple subtitles embedded. Here are my questions.

1. Some of my dual audio files allow me to change the language while others don't. What is the cause of this?
2. Some files all me to skip forward or rewind 10-15 secs and some don't. For the files that allow it, I can also time search in 1 minute intervals.
3. I have a subtitle option on my tv but it is always grayed out. Anyway to enable subtitle selection?
4. I don't mind transcoding as my system can handle it. Are there settings that I can play with to enable some of the options mentioned above?
5. Is there a new version coming out soon? I've read a few posts that date back to year that suggest this.

Any assistance with these issues will be much appreciated. Thanks
