If you have HD DTVR Service, you can't record and watch but if you have SD DTVR, you can. I know it weird but due to the fact that HD uses more bandwidth than SD so Sasktel needs to come and change to SD in order to record and watch but if you have HD TV so why do that? Eh? I know it be nice to watch and record the other. When they have more bandwidth coming soon, they'll do it eventually, so i guess you have to just watch and record same time.
VDSL2 should be launching later this year, which will enable enough bandwidth for at least 2 HD streams. Once this is launched their will be a software update for your MAX box so that it will work for recording one channel and watching another.
