f5s timeshift problems

I did a search but cant find a lot about timeshifting and nothing answering my question :(


decided to set the timeshift back up on my f5s... got a 32g usb and had no glitching or stuttering problems... however i noticed on slysports and the movie channels it doesnt work...cant pause or rewind or anything.... the other channels seem to work fine though..... can anyone please tell me the correct settings ,if there is any, to make it work???
