Please recommend compatible media for my Panasonic digital recorder

I am thinking about getting one of these Panasonic DMR-ES40VS DVD recorders for my dad, who wants to convert old VHS tape movies to DVD.

How finicky is the dvd burner in this recorder about DVD blanks it uses?

I’ve got some Sony Tayo Yuden ones, but if the drive is not too picky, I’d als like to pick up some of those Staples 8X DVD+R made in Taiwan (CMC Mag) blanks when they are on sale at Staples?

Also, how do Verbatim blanks do?

I just got a Panasonic DMR-ES40V digital video recorder.

Could others recommend some compatible media?

I am looking for both +R and -R recommendations, both in a budget category for everyday recording and a more expensive archival quality blank for converting old VHS movies to DVD.

Thanks in advance!
