I have searched all over the web, searched this site, etc. to find out whether the Value Disc brand DVD-R sold at Office Max is compatible with the Panasonic DMR-E80H DVD recorder. When I asked the employee at Office Max, I was told that it was my job to find out, not his. He did tell me after I asked if there was a website for the value disc company that they were made by Ridata - but I can't find anything to confirm that this is correct either. Thanks!
