avermedia C127 using hard drive space when not recording

[shiggy74]

Hi Team,

I know this is probably a stupid question but I just brought a avermedica c127 and have not recorded/captured anything with it yet I am just playing my xbox one through it. But I have noticed that it is still taking disc space even though I have not recorded anything. Does anybody know what it is actually doing to be using up the disc space.

Thanks in advance.

I don't have the Avermedia C127, but I know many similar cards have a DVR type function that buffers the input stream so you can pause and rewind live TV.
