DVD-r going weird

[humet]

I have been using these DVD-Rs from gogodisc.com and they were working perfectly for the first 30 movies I burnt, but in the last 10 they have started going weird; the movies have started jumping towards the end of the movie, and sometimes not even playing. I am using a Pioneer A04.

Please help.

Thanks

There is no help, some of them are bad.
