Intel driver 15.65.3.4944 seems to work. No failures so far.

I have done more testing with the latest driver and it's far better than previous version. I still get a few failures, but it's a huge difference.

All drivers released after version 4771 directly caused failures, i.e. conversion of any video failed approx in the middle of the process.
With version 4944, I did not see any single failure for 4 videos.

My CPU is an i7-7700K running on Windows 10 64 Bit Fall Creators Update, build 1709.

I use these settings:
--disable-qsv-decoding
--encoder-preset balanced
--qsv-async-depth=3
--encoder-profile=high
--encoder-level=4.1
-q 21.0

@rbirk: What are the scenarios where it fails? What are your settings? Would like to reproduce the failures.

See previous posts with full logs. It's all old DVDs. I have finally started converting my big DVD library to hard disk and its 1000+ of them. So I am converting many movies. I usually put 30-40 movies in a queue at a time.

Hmm, I've now seen a failure with version 4944 (where version 4771 succeeds).

@rbirk: you are right - version 4944 is more stable than previous versions but still not as stable as version 4771.
