A DVR-A07 problem?

Hi everybody,

I never fail to burn dvd-r on my dvr-a07 burner , both data and video. I had no problem of accessing the media using the same drive, but do have read problem using other DVD-ROM. my Liteon DVD-ROM and Compaq laptop DVD-ROM fail to access all the files that I burned. It always have some files that cannot be access, system just hang. But surprising if I use the DVR-A07 burner to read, I had no problem at all to read all the files. I had tried many media, verbatim, imation, etc … but same problem…

Anyone got any idea what happened? Pls help.
