After using AIRTEL HD RECORDER I am very much satisfied with this product.
Reasons:
You can record two channels or programes at the same time, means when you are recording a programe on channel one then at the same time you can record another programe on channel two with the same recorder at the same time its really interesting.
You can watch one programe and record another programe at the same time.
Record two different programes at the same time and you can play one recorded programe at the same time. Means three work at the same time with one HD Recorder( HD DVR). Its tooo good.
Due to these facilites you can also save lot of time by forwarding advertisements.
Suppose during recording if electricity is disconnected, then when electricity come back the recording starts automatically. If you are busy with your work then record programes and watch at your convenience.
It also has lot of space for your recorded programes, recorder has a storage capacity of up to 550 hours approximately, recorder is now 3D ready!, Dolby Digital Plus 7.1 surround sound, HDMI output .
