check what format you're recording the dvd's to. also check your manual for the dvd player. If the dvd player doesn't support the format you're recording in, it can't play the disc. Also, if the dvd player is relatively old, it may not support as many formats as most newer dvd players do.
I bought a Sony DVDirect unit to record digital photos and videos to DVD. The unit allows me to record directly from my Compact Flash Card to DVD-R without going thru the computer OR I can record to DVD+R using the computer's DVD recording drive. I can play either on my computer after recording but neither will play thru my TV's Sony DVD player. Any suggestions? Thanks in advance.
