Hi all, I'm fairly new here. I just pulled the trigger and ordered a BOLT VOX 1TB, two Mini VOX's and all the parts to upgrade to an external 3.5" 4TB HDD, connected to the internal SATA connector. See the following post for details on those parts. I welcome any advice about the HDD that I chose. MFS Reformatter (mfsr) I've searched a lot on this site and I haven't found much info aside from references to Plex and pyTivo about what media formats are natively supported by the BOLT VOX. For example, can the BOLT play mp4 or mkv files (with mp4 video and ac3 audio inside of the mkv container) from a NAS or from an external HDD that is connected to one of the USB ports on the BOLT? Is this ONLY possible with Plex or pyTivo? Thanks, Brian P.S. - If there are any "how-to's" or "stickies" that I should have read, please direct me to them. I didn't see any. P.P.S. - A little background about me: I've been using Windows 7 Media Center since 2011. At one point, I had 10 tuners and 5 TV's connected to it (4 with XBox 360's used as extenders). Right now, I have 6 tuners (Silicondust HD HomeRun PRIME CableCARD tuners) and two XB360 extenders. I have been waiting for a LONG time for Silicondust to finish their DVR solution. I donated to their Kickstarter campaign quite a few years ago. But they STILL do not offer the ability to record copy-protected content... so I converted to Tivo today.
