Just thought I would post this.

I know peolple have been ragging nero, me being one of them.

All my backups would play fine in standalones except my LG3200e.
I would burn with UDF/ISO 1.02.
I thought it was down to my method in ifoedit read the guides,stamped the feet and threw the toys out of the pram but to no avail.

2 weeks on the same problem reading the various posts and came to the conclusion it was the LG3200e.

Just tried something out and succes at last - plays on all AND LG3200e.

I just burned using UDF only not UDF/ISO.

I know this probably won't be the same for eeverybody but did the trick for me.
Give it a try.
