HDHR Dual software settings?

Hello

For those of you using a HDHR Dual (QAM/ASTC) version, what setting are you using in the HDHR software? WIth the upgrade to windows I upgraded the firmware version from 04012015 to 08262015 and am experiencing difficulty with playback "quick advance" or fast forward at either 10 sec or 1 min intervals. I was recording under the default setting, should I be using the NextPVR setting instead?

Thanks!
