Could be a few problems.

One is, do you know 'if' your home dvd player is able to play dvd+r disks? Find out. (Some dvd players cannot play dvd R disks. And some older ones only play DVD-R, not DVD+R)
When you burned the disk, did you choose video-movie format? If you burnt the video file as a data disk then the dvd player will not recognise the format.

One way to find out is open the disk up on your computer & see if it has both VIDEO_TS & AUDIO_TS folders inside. However this still will not guarantee it will work but if it does at least suggests the video was mpeg2 formatted correctly. If it does have those TS folders then probably the problem was the actual dvd format burned at. It needs to be officially UDF format but on dvd burning programs this is usually simply called video-dvd format or similar.

Using decent brand dvd r disks not made in taiwan or china helps.
And do not burn at maximum speed. This is important for video dvd's.
