Another new firmware available today haven't as yet check it out

Unfortunately the new firmware still hasn't corrected the slow playback when playing music videos with a 96khz audio track via the inbuilt media player. This has been the case for at least the last three firmwares An earlier firmware correctly playback the 96KHZ audio track unfortunately I can't remember which one it was. Can the firmware design engineers from Zidoo fix this problem please.

I bought one of the first Q10Pro's many years ago from futeko (always had good service), at first the firmware was a little bit wanting for correct playback of 4K HDR but over the years particularly with the Custom Firmwares (which I still use) playback improved. I have since purchased an Nvidia Shield and a Zidoo Z9X (again purchased from futeko) both of which are very good, the Zidoo is particularly good at 4K Dolby Vision (the main reason I bought it). But today I just reinstated the HiMedia out of interest after around a year of not  using it at all and was very pleasantly surprised at how good media playback was still, in fact it was on par with both the Nvidia and Zidoo. The HiMedia is still up there, it's a pity they haven't got any quality new models with more modern chipsets available like the old Q10Pro.

I am using a Z9X with the latest beta firmware and found that when I play the soundtrack of bluray audios within the zidoo media player set to LPCM 2.0 96khz that the sound plays back at double speed. If I change to the 48khz soundtrack all is well.

I have recently been using an Nvidia Shield Pro and results were generally very good apart from  Dolby Vision support and the recent update to Android 11 which had many problems. On checking various Forums and media player reviews I decided to give Zidoo a go mainly due to its 4K menu support and Dolby Vision support. I decided to go down the Zidoo Z9X route as all the players had the same video engine albeit with slight ram changes and my main interest was film playback (not music playback for which I use other equipment).
My initial impressions on unboxing was what a poor mains adapter I just couldn't get the plug arrangement to work and the minor problem lack of batteries for the remote. Surely in this day and age a proper mains adapter for the country could be included or a better designed multi type of connecter setup of which there are many so much better.
Moving on to the positives I am very pleased how the box operates particularly handling of 4K menus and Dolby Vision support and also the picture quality. Initially I thought the picture quality was a little soft and lacking in color pop but with some adjustments and with some running in time it is now fine, possibly just a little bit better than the Nvidia Shield.
So at the moment I am pleased with my purchase of the Zidoo Z9X and appreciate the rapid delivery from Futeko but please get a better power adapter.

Does anyone have any thoughts re Dune HD Max Vision 4K v. Zappiti Pro 4K HDR media boxes, which offers the best value and features particularly regarding operating software and Dolby Vision in particular?

Just changed to Custom firmware Lite 2.1.7 finding it excellent better for me than the fuller version which I have used in the past. Is it recommended to update Kodi to the newer version 19 from pcristi's  mediafire kodi folder?
