Sanyo DWM-370 (May 2001)

http://www.walmart.com/catalog/product.gsp?cat=62055&product_id=1242605&type=1&path=0:...4552&dept=3944

Softwares used:
Using Sonic MyDVD 5.0 Dx
Ulead DVD Picture Show 2
Momeries On TV

I have made some picture slide show using the above software, I was unable to get my Sanyo DWM-370 DVD (standalone) to play ANY of my home made slide show in DVD format discs or some VCD, SVCD ok. Is this player not supported or is there another way to tweak the burning software...?

Any ideas?

Thanks !!
