@ Karthik.....yes that boot time is normal. It will keep increasing as u keep adding recordings to it. (Obviously!) But its true that the DVR checks HDD whenever u switch it on. And about the channel change time first up.....well its a technical thing actually, which is not working properly since few days.What used to happen earlier, is that they had a Welcome message with their CC contact details (IINM) provided, when it started up. And it stayed there for few seconds. Till it stayed, u had to wait. And thats logical too, coz ppl might want to note it down.But these days, that message itself isnt appearing, but that waiting time is still there. Its nagging alright, so i guess they shud be fixing it in an update (God knows when).@ vicky.....It will take some time here. And that 24 hours thing is pretty consistent as well. Around atleast 90-95% of the times, they get back within 24 hours, and finish the installation & everything. In few cases it might take upto 72 hours. It wud be done surely within that much time.And btw, do remember the thing u need to keep in mind for installation......1) U have HD box. So, without any compromises, the Signal Quality shud be 99-100%. (I forgot to tell u, that when that guy installs, the screen will show 2 Bars - 1) Signal Quality, 2) Signal Strength.)2) Signal Strength, shud be atleast 90%3) Now this thing depends on ur preference: If u want Universal remote, u get after the engineer to do that setup for u. Its ur right to get it done.4) This applies, only if u opt for Universal remote......before that guy sets it up, ensure that the Sound of ur STB is at its Maximum. Because after Universal is done, u wont be able to adjust STB sound.Say if that is at 80%, before the setup is done, then it will stay like that forever, until u segregate both remotes again.
