I really would like to have a PDF manual of Mezzmo. Is one available?

Could Conceiva create a set of reference files which would allow us to test Mezzmo with our (new) DLNA media players?

At the moment a PDF is not available, but there are free tools out there that let you convert help files to a PDF format. We'll look into creating one.

Regarding reference files - I'm not sure exactly what you mean by that. I mean, the DLNA standard is mostly around MPEG2, AVCHD, MP3, LPCM, JPEG and PNG. Other format support is what the hardware manufacturers decide to put in their firmware. If you could tell me a bit more about this, perhaps I could understand better what you wish to test.

I am probably asking for the impossible. It seems that there are too many combinations. But I am specifically looking for video files. A set of the most common formats which give the most headaches as well. If these files are installed as part of the Mezzmo installation in a test folder, it would allow us to verify most common files are played / transcoded correctly.

Ah, ok, that's what I thought :) Well, as you understand, it won't do much good, since it won't actually tell whether a ripped BluRay using software package X that you use will be successfully transcoded to play on your device or whether a downloaded movie from somewhere coded by some group will play, or if a recorded show from your TV recorder can be transcoded, etc... Unfortunately the real world of videos is a huge mess.

We have a set of files that we test devices with - they take approximately 1TB of disk space, but they do cover lots of common scenarios.

I am more concerned about the headaches I had with my various TVs I had in the past all sporting a DLNA label and never working that well :(

Sure, but common formats won't help there either, since a TV's manufacturer can implement or not implement something that's not entirely DLNA-standard. For example, one TV can play files of a certain format at a certain bitrate, another is not limited, the third is not limited by bitrate, but by a certain encoding level. It's just impossible to cover all possibilities and ship such test files.

What Mezzmo does, is that it transcodes any combination of your input files to something that the device should handle (according to our device profiles).

You can also check DLNA capabilities of your device using the http://www.dlna.org site which lists all certified devices and what they support (as a minimum).
