I have LG DVD RAM drive . HL-DT-ST DVDRAM GSA - 4163B I recently bought a DVD vedio , it has a size 7.5 GB. Sometimes my DVD drive doesnt detect it at all. Else, it detects it and plays or rather opens only about 25 % and then it keeps reading errors or it just cant proceed , ALso it cannot read the end parts of the movie( after that 25 % nothing is read ). It can read and write other DVD of 4.7BG and CD fine and well enough. Why is it so ? What should i do ? its still in the warranty period. Can u suggest me good DVD ROM and Combo drives and list out the prices of them. ? SOS PLZ help . What should i do about this problem with drive ??
