- Fixes the issue that NVIDIA hardware encoding is not utilized when burning discs with the H.264 interlaced profile.
The good news, yes v2514 appears to address the lack of GPU functionality in the Create Disc module posted here,

The attached pic1 shows the two interlaced results from v2408 and v2514 and indeed things appear to be functioning as desired.
I do think an issue surfaced with the current Nvidia 347.09 drivers and PD13 that CL should be made aware of. I've seen significant loss in HA encoding performance for some formats during "Produce". Yes, one might say it's a Nvidia issue, however, the PD "Create Disc" module with this release does not appear to have the same issue with HA so I suspect the fault lies with PD and the "Produce" module and info being passed to the Nvidia NVENC encoder.
This issue is shown in the attached pic2. For the profiles shown, for some reason the "Produce" module is about 1.4 times slower with HA with Nvidia driver 347.09 vs 344.75. For example, the elapsed times 725 seconds vs 511 seconds for the same profile from Run ID 5 and 6. This effect is not seen in the "Create Disc" module with the same video profile settings. Run ID's 9 and 10 in the "Create Disc" area show no significant difference with either Nvidia driver versions. The performance decrement is also very video profile dependent, both source and output. The worst I've seen is ~2x longer so not trivial for a NLE that claims encoding performance as a consistent product differentiator. High level parameters of the video files like bitrate, size, are consistent as well as a visual look of quality so the additional encoding time does not appear to be reasonable.
