SD can not read

Best non-professional answer removed as not good enough for OP :>D

When you install a larger SD card it will be a fresh empty memory card. Your existing 8Gb SD card will still have the the 5 hour gig data on it.
You can insert the 8Gb SD memory card into an USB memory card reader and plug this into the USB port on your computer. The computer will see this SD memory card and adapter as an external storage device. You can then open the audio folder on theis SD memory card and copy this file to your computer.

try loading the audio again on your computer. maybe it didn't load properly. also try switching the technics deck off and back on. maybe it is having a bad day and needs to restart.

To achieve MPEG2 video performance, large amounts of data must be written to the SD Memory Card in real time. The read and write speed of the SD Memory Card may differ from manufacturer to manufacturer, so we recommend using Panasonic SD Memory Cards with the high-speed transmission rate of 10MB per second (SD Memory Cards that are 256MB* or higher have a transmission rate of 10MB per second). FINE Mode recording (High image quality 704 x 480 pixels) recording requires an SD Memory Card that is 256MB* or higher. NORM Mode recording (Normal image quality 352 x 480 pixels) recording requires an SD Memory Card that is 32MB* or higher. *Usable capacity will be less. The use of SD Memory Cards other than the ones mentioned above may result in the following error message: [This card cannot record in MPEG2 mode.]
