It was more like audio drop outs. as though the pc was havig trouble reading the data almost, and then I noticed my external was running like crazy and the cache bar on the left of the transport bar was shooting all the way up and back down during tyhe playback attempt. After I moved everything back to the pc harddrive. Everything is ok now. the only other thing I noticed was my external drive is a fat32 format, not sure if there was some conflict with the pc being NTFS? But I start back recording this weekend. Pray for me.
