Server Version#: 1.41.0.8994  
Player Version#: 1.41.0.8994?  
Tuner Make/Model: HDHomeRun FLEX 4K  
Guide/Lineup name: Local Broadcast Listings  
Using XMLTV?: No  
Channel number/Name: all

hardware acceleration has broken in some release, not sure when. Logs are below. Server specs: Windows 11 pro for workstations 23H2, intel i9-12900 processor, 128GB Ram, ARC A380 graphics card. I’ve tried this with hardware accel ‘when available’ using device ‘auto’ and device ‘A380’. The errors I get when tuning to certain channels are below. I tried deleting the codec folder (from another thread), no joy. The only fix seems to be to disable hardware accel. Graphics drivers are up to date.
