I have used this facility for tata sky +hd but never tried for adtv.
For recorder it should ideally work. But since the interface is so bad and not all channels available i did not try ever.
Now since you are using hd+ my suggestion would be that when you try internet recording keep the channels of tv on same channels for which you are selecting program from internet account. Hd + works on single wire and watch same record same technique. Try this and let me know.
