My opinion only:
With single-layer DVD media, buying Verbatim is not as complicated as it once was.
Some time ago, Verbies made by Moser Baer India Limited were considered by many to be inconsistent.
These days (again IMO), things have changed a lot and evened out quality-wise. The Made in India DVD+R are actually my favourites
So if buying single-layer Verbies, I wouldn’t worry so much about the Country of Origin.
DL media is a bit different - the absolute best you can get are Verbies that are Made in Singapore. But recent reports seem to indicate that the Made in India ones aren’t so bad.
If you’re in the US, www.rima.com is the best place to buy online. If in the UK, then there’s www.svp.co.uk - however, I don’t think there is a way to tell the COO with mail-order purchases.
Others may have different opinions or more to add.
