I have been burning DVDs on my Mac for years using Toast 11. Recently I have had regular problems burning video to DVD-RWs. I had always used Verbatim, sometimes Maxell, DVD-RW, with no issues. Always a useful process to check the contents, picture quality, editing etc beforehand, is my thinking.
In the past 12 months or so, I get regular refusal to burn to the DVD-RW. I get error messages but both the Superdrive and my external player refuse to use DVD-RWs Do they have a shelf life? My initial though was they were getting old, repeated erasing etc etc. But even newer DVD-RW s are rejected. I also note recently I have problems re-using CD-RWs as after 'erasing' them the contents is still there (even if I select option to erase fully). HOWEVER if I take the risk of burning direct to disc DVD-R invariably I have no problem (except I find I might have wasted a disc in the process!)
Could the issue be that I am using a more recent Mac OS (High Sierra) ? Or is Toast 11 the problem ?
Or is it simply DVD-RWs wear out quickly?
