I have more or less the same remarks, please see my last correspondence. In
summary:
1. there is only one stream processed the VGA or DVI, and the 'selection' by
core is random (?)
2. 1h30 min recording has failed for me too, and strangely enough it was
process by the server but nothing came out
3. <<<The fact that there is no way to see the files on the ECD and download
them from the device in case something goes wrong is also a big problem for
us>>>
And not only for you! You just have confirmed that captured recording
can be lost and unrecovered.
I think the feature of accessing the device storage with option of
uploading the last capture to the server, is obsolutely essential. I am only
repeating what I have already said.
Without this feature, this device is practically useless.
4. <<<This experience leads us to wonder if this machine is production worthy
and if anyone is using this in a reliable way.>>>
Well, it is certainly not! In the current state I would not dare to use it
even in a pilot project.
The question is what next?
I am now very pessimistic about the progress. Or the device hardware is not up
to the job - Greg complained about the memory size? Or the software has not
been properly designed from the start?
I've got a feeling that Epiphan will release truly own MH compatible capture
device. The Lecture Recorded 2
http://www.epiphan.com/products/recording/lecture-recorder-x2/
they have released last autumn makes me think.
Let's hope and wait or try something else?
