Yes, that's another very reasonable possibility.I am guessing that the 8300 is missing some 'functionality'...
It'd be nice to know for sure what the issue/requirement is so that we could say "if you want to play BR then GPU with minimum capabilities X, Y and Z is required". For now I'm not familiar enough with the libbluray/BDReader code to be able to make that determination.
Okay, so I guess it's not a DXVA issue then. Thanks for checking.I tried to run LAV + EVR + 8300 with DXVA disabled (log file attached) - no background image to language menu, and interlaced lines in place of menu text.
(I asked because as I recall, DXVA used to make a difference for DVD menus sometimes.)
The only tip I can offer on this front is: make sure you don't have sync correction enabled in both LAV audio and MPAR if using both together.Now 'all' I have to do is sort out why the A/V sync with the GT710 is very hit and miss and I'll be in business (plenty of threads here for me to work through )
As time allows, I'm still looking into the previous MadVR log files you've provided. I'll let you know if I find anything worth testing.
