Your vintage DMR-E80H likely has two issues when recording to DVDs. The first is media. The second is cleaning of the laser lens and rubber hub atop the DVD Drive spindle (turntable).
The E80H was designed for use with DVD RAM or 8x DVD-R blank discs. I suggest using only the best quality 8x DVD-R media. That would be JVC/Taiyo Yuden Premium Line 8x DVD-R media sold by SuperMediaStore, Rima and a few other online stores. This is what I use in all my Panasonic, Magnavox and Philips recorders:

The usual way to service a DVD Drive in Panasonic recorders involves removing the outside case cover and the DVD Drive lid. With 2004 and more recent Panasonic recorders the procedures are simple enough. Not so with earlier models that have the DVD Drive contained within a metal surround structure. For that reason I refer you to the advice found in this post:
