LG External Writer

Hello. I recently purchased a new writer after my Panasonic crashed and was curious to know if anyone was having the same problems I have been having. I have the LG GSA-E30L and it seems that every disc I have burnt on the new burner is having playback issues. Towards the end of the disc, the video becomes pixelated and stops working momentarily (average 10-20 minutes of video). It seems to occur on every disc I have burned since I changed writers. I am using Fujifilm DVDs with various programs (Shrink, Nero, DVDFab, DVD Decrypter, etc.) and have been for many years. This is the first time I have experienced this issue. Thoughts?

Thanks.
