Multimedia DVD problem

[PKD1256]

My PC configuration OS : Windows7 Ultimate, Drive G : Samsung DVD-RW.
Earlier I was able to run DIGIT AND CHIP multimedia DVDs. NOw only DIGIT DVD s are being played. With CHIP DVD Drive G shows only CHIP icon.
With Audio CD there is no problem.
Digit DVDs having File system UDF while CHIP DVDs having file system CDFS.
Please suggest solution to the problem.

Its a common problem and sometimes depend upon the DVD writer. I haven't found any solution of it apart from changing the Drive.
