Hi

They look about right to me compared to a similar server I have here.

Did you read this little but “Translation times between formats (in microseconds) for one second of data” not miliseconds that it used to be.

Hi

you would have to download source and patch that then compile.

But looking at it, I wouldn’t bother, how often do you need to do core show codecs ?
