code -536870198 when trying to burn memorex dl
6.33 gb 1hr 8min iMovie on desktop, using Superdrive dl burner, memorex dvd-r dl disc (8.5 gb 8x 240 min), tried slower burn speed 3x, still unsuccessful. Aforementioned code comes up after about a minute. Apple support didn't know, suggested trying different brand disc, so purchased Verbatim, arriving tomorrow. Does anyone else have same problem? Superdrive is new, it plays other movies perfectly. My Mac is 2015; using latest version Monterey 12.7.3. Have not tried burning shorter movie or single layered disc. However, my old disc burner worked perfectly for that.....just having problem since the dual layer thing.
