All stations (Subcription}I don't use DOL and Mobdro also blows.
On Kodi and Off of it.
My Shield side by side with the T1 does NOT lag at all....I guess The shield is much better with paid tv...….JT
If DL is like other STB's that have dedicated Stalker programs to access the Services(DOL, MyTVOnline etc), my observation from testing indicates most implement dedicated video decoding hardware and Firmware that many Android applications like Kodi, cannot use because the Android OS is not real Google Android, but a modified version that have omitted the MediaCodec (software interface) to properly access the Graphics Processors.
The dedicated stalker Programs appear to have proper interfacing code to use all functions available for decoding of the Video streams.
Since the main use of these STB's is for IPTV Service using the built-in Firmware, the memory and other resources are not more robust than what the main program requires.
Case in point would be Kodi.
Installing Kodi on a STB that has 1Gig. of Ram, and expecting it to work at all, is dreaming.
Yet using the built-in LiveTV or VOD will play perfectly(Though a little bit sluggish executing peripheral functions like Guide data loading, EPG scrolling etc.(2Gig units do not exhibit this problem)).
Perfect Player is a better alternative as it is not as resource heavy as Kodi and has HW Acceleration driver code that can use most Graphics Processing functions.
* Note: Nvidia Shield is one of only a handful of Quality STB's that have proper firmware to utilize Hardware Acceleration drivers fully, as they use real Google Android OS's API interface code in the Firmware.
Just my observation...
