I have had an X9s for many years and it works well. I use it often for HDMI recording. It is connected via an HDMI splitter to a Sky box, with the X9S HDMI output connected to my venerable TV, a Sharp LC-37X20E model. It has worked flawlessly.
I recently upgraded to a Z9S, just replacing the Zidoo and its power unit, everything else unchanged. I soon found a problem – it would adopt one of four symptoms, seemingly at random. Either a good recording, or a loss of sound part way through, or a completely garbled sound plus a very jerky picture in the mini window or a complete crash to a dark green screen followed by a reboot.
I tried all the settings I could find for both picture and sound, I copied down all the X9S settings and applied those, tried a full factory reset, checked on latest firmware but nothing fixed the problems.
Further investigation revealed that the trigger for the problems was changing the input selector on the TV and it was OK after selecting away from the Zidoo, the problems occurred at the moment of going back to the Zidoo. I retried the advanced settings for HDMI but still no change. I tried a different TV and no problems occurred.
Redoubling my efforts I eventually found that disabling the picture EDID, it’s under quick settings, display then turn on “Ignore EDID”. I don’t think the X9S has this setting.
Hope this helps somebody!
