disable "live tv pause buffer"?

**EshiKaa** · 10-05-2008

This is my very first Media Center PC (Gigabyte). I love watching Movies and live tv on the same. The only thing making me trouble is its "live tv pause buffer" feature because it heats up my hard drive very much. Usually I just watch programs and never record them, so I don’t want this feature in any way.

I tried searching for option to turn it off but dint found it anywhere. Can you guys please tell me if there is any method to disable the same? Many thanks.

Heating up hard drive is normal upto 45 degree. How much temp your Hard drive going to? Did you checked the temperature with any software? See how much is it going to. My hard drive usually goes upto 43C while watching in Media Center and that is normal.

Hello EshiKaa, if your hard drive is eating up too much space then there is a way to decrease it. I did it using a script containing registry settings. Simply paste this code into a text file and save as .hta It lets you choose # of files and total size:
