First thing I would check out is the brand of the DVD you are using. When I first made inquiries as to the brand of DVD professionals in the industry use, they all recommended the same brand, Verbatim DVD-R. Suggest you make your own inquiries as I am not out to promote any DVD brand.
Second thing to check out are the particular DVD players that will not play the DVDs. DVD players have a specification called a Sampling Rate. Quality DVD players have a greater Sampling Rate that will read the DVD multiple times as opposed to cheaper DVD players that have a far lesser Sampling Rate. To eliminate this possibility, suggest you play one of the alledged faulty DV’s on a modern Sony DVD player manufactured in Japan.
Both the above possibilities have resulted in skips and freeze problems when playing DVDs.
Trust the above helps.
