pvr cache settings in advancedsettings

Hi,
Can someone explain why the pvr cache settings are dropped in Kodi 17?

I used to work with this settings:

Code:
<advancedsettings>
<pvr>
<minvideocachelevel>20</minvideocachelevel>
<minaudiocachelevel>10</minaudiocachelevel>
</pvr>
</advancedsettings>

and they worked great for channel swapping.
Are there alternatives to these settings for Kodi 17?

Thanks
