@Bowie70 I think that you got a particularly bad introduction to what SufferFest can be. Cadence Builds is a drill session with no music or storyline, NoVids have no video at all, Running With the Wolves has a record of being hit-or-miss (see here: Running With the Wolves - I am Confused ) and GCN videos are basically spin classes.
It sounds like you’re in a low-intensity week of your plan; try sticking with it a bit longer, and next week should move away from that. Or, you could swap in some Sufferfest videos, with the black/white/red flag icon (though don’t do this regularly - you don’t want to miss out on the recovery built into the plan). You may well find workouts that are more engaging, and challenging for reasons other than enduring watching the video
If you’re having bad quality playback, though, I echo the suggestion to try downloading the videos, and if that doesn’t help, contact the Minions.
