Well its a sturday and I didnt really have anything else today , woke up at 6am and there was no electricity , so I decided it was time to use the new Tata Sky + DVR STB in a diffrent way :D.

So I decided to open it up to see what they have hidden inside , what kinda upgrade we can try ourselfs to get more recording time , can we transffer the recorded videos to a PC ....and guys the answers were all positive!!!

Opening the Tata sky STB is one of the easiest experiments I have ever done (this may vary from person to person , opening your STB up causes your warranty to be void , so please do this at your own risk - this is not my responsibility nor is it the forums , but all I can say is its very hard to do something wrong and mess it up ) .

Opened up the 5 screws of the STB , one on each side and 3 at the back of the stb , this causes the upper lid of the STB to slide off , so once the screws are removed just gently slide the top of the STB open.

I didnt open this up to see what they are using here (this is for another experiment another day.

The good thing is its a regular SATA Desktop (not laptop) HDD.
It Can easily be replaced with another HDD say a 500 GB increasing your recording capacity by 3.5 times :).

To see if this is possible connected this HDD to my PC :
Vola.... The file format is FAT 32 !!! so what you would ideally need to do is
Buy a new SATA - Desktop HDD - create one big partition and format it in FAT 32 and then connect it to the STB and it should simply work (I havent tried this yet , but will do it next week , but i dont have any doubts it will just work).

The good thing is in case you have recorded something important and you need to transffer to the PC you can do it this way (since the file system is FAT 32!!

After all this o just put back everything to gether , and switch on the STB and well everything just worked like nothing happened :)
Feedback appriciated!
Updated with trying to copy recorded content here.

Yeah will work on the 5 minute recoding (may not be possible today , dad just chased me off from the TV area : he wants to watch the match).Yes FAT 32 will have a 4 GB limit but the DVR will split the recorded files into multiple parts for senarios where recording is scheduled for long hours. I Should have first recorded something and then removed the HDD in the first place but there was no electricity at the time when i started opening up the STB :wall:

Great work there! Really appreciated. Now a few more questions.1. Did you notice the network controller chip? What make/model?2. What about the USB controller?3. Need you to record something for about 2-5 hours and check the files on the computer using some codec information tool. Will give us an idea about the encoding and bitrate.With this information, I am sure someone can come up with a hack to either connect this to a network or to use some kind of an e-sata cable to directly use the recordings on the computer.Great work nonetheless. Keep it up.
