Freezing and Restarting Shows

So on one of my Samsung TV's the app was rolled back to the previous version which by the way works great. Now I am still having issues of freezing live tv, restarting recordings because if you fast forward too much it freezes, I get a lot of heavily congested etc, which is hilarious at 5am. Recordings that record with no sound, so I have to watch on demand. Being trapped on certain stations because there is a circling circle while it is frozen. I cannot count the times I have to restart my internet to be free of that. The fact that the guide doesn't show favorite stations or tells me I don't have any favorites. This is insane- and who ever is going to suggest that I buy something to watch Directv Stream on my Samsung, I shouldn't have to. That is the whole point of streaming TV!
