Trying the demo, I thought I got vp17 stable by installing the latest driver for Intel UHD 630 (built-in graphics). I have the I7 8700K and no external graphics card, running Windows 10 1803.
Then after buying vp17 I found it *sometimes* unable to load some previously saved projects from the demo as well as projects saved in vp16. Then *ouch* I found vp16 no longer opens some of its projects. In both cases, the program seems to load up the bin, then load up the timeline, then disappear with no visible message or diagnostic. Some of these projects are just jpgs with pans & crops & titles & occasional fx like colors/levels. There are related events in the Windows event log.
For both vp17 and vp16 I worked around this by disabling "Enable QSV Encoding and Decoding (where available)". So it seems clear the new driver triggered a new problem for both versions.
For vp17 demo with the older Intel driver, the program would hang after loading and starting to edit. These hangs could happen seemingly any time, though noticeably often when playing somewhere in a Sony "Titles & Text Plug-In" event. When it hangs, there does not seem to be a way to generate any diagnostic. I never found a way to reliably reproduce this. And it went away when I updated the Intel driver.
With the new driver, both vp17 and vp16 disappear and generate Windows error events when opening their own projects when "Enable QSV ..." is set. Here's one:

Bottom line, I'm up and running without the QSV enc/decode, and otherwise there are some problems that seem related to the Intel driver, but I have no reliable way to reproduce them. I will report the diagnostic above to Magix. Otherwise, I need to come up with a simple project that reliably causes these problems or else come up with a version of the Intel driver that cures both problems.
