I had a request to add the option to change the Sample Freq from 44.1 to 48 using my tool - simple to do in the registry but as soon as MMC 7.5 starts up it deletes any profile that has Sample Freq of 48 KHz.

This is confusing because there are DVD presets in MMC 7.5 but the audio is set to 44.1 when the DVD standard is 48

see the specs:

I've tried upping the bits from 16 to 24 also but it still instantly deletes any profile set to 48Khz ??? very strange - if someone can figure it out pass me the info - I'm puzzled by this one.

patrickm??? next?? help me out fellas!
