Recently I have checked the advanced system settings. And turns out it's not even a bug. Previously as I remember these 'Auto Standby' & 'Power Saving Mode' modes were off by default. But with the Tata Sky pushing the firmware auto-update, these modes have turned on.
With Auto Standby turned on, STB functions the same at specific time which is set. The scenario is same for Power Saving Mode by functioning according to it's characteristic.I confirmed the same with TS IT department by emailing the HQ. And they also advised me to keep the modes off. Then my question was that if the disk goes to the power saving mode then why my scheduled programs were being recorded with no problem? For which they responded with working on fix. In addition, they also accepted that these modes doesn't make sense for STB with DVR facility.
