Your home theater system's product description says it will play the following disc types --
DVD-Video, DVD-RAM/-RW/-R/-R(DL), +R/+R(DL)/+RW, CD, CD-R/-RW, Video CD, SVCD, WMA, MP3, JPEG
Looks like it covers about all the usual video disc suspects (except Blu-ray
). Are you burning them as DVD media? It
should play your -R discs... maybe it doesn't like the brand?
