Okay...I calmed down and tried again. I removed every single add-on I could get by with,my pop-up filter,deleted every cookie,etc.
Logged in,clicked on the first concert I saw(Kansas) and tried a couple times,with it doing the timed out thing. I tried the 3rd time and it started,and that dang "buffer full" thing showed up again...BUT for only about one second. It continued to play,even after the buffer reminder. I listened to the whole show,but at the start of each song the "buffer full" would show for that one second every time. But it played great.
Hit and miss,I guess. I then tried the Blackfoot show which is where all my troubles started. It did the same as the above show.Excellent recording. Ten bucks?!~ a steal!
BTW,the Kansas show with Steve Morse on guitar is excellent.
Hope this helps,but I have no clue what was the deciding factor in successful playback.
