bri46 posted a topic in ChatPlayer recognizes 4 GB file as "DVD-R AVCHD" then plays as Single layer disc fine.. Taking 8 GB file on same type disc and format on DL, player calls it a "Data dis"c and says "file not supported". SAME disc (created in Image burn which selects best break, plays fine in 5 year old Panasonic Bluray player! Original format created in IMGburn for copy to DL disc are ISO and MDS. Sony says use +R which did not work or use older model? Any thoughts?
