If DVD +R and - R work, then which is better to use?

[i am x]

Ok, any help would be appreciated. If you have a DVD player that can play +R and -R, then which one is a better format to use, as in which one will give you fewer errors when viewing, considering nothing is wrong with the footage to begin with? Let me be more clear. [Before I begin with the explanation, the discs I'm using are Ritek G04's]. I have a certain customer that views a product that they bought from me. In MY DVD player, the product I sold them will play without a single hitch/glitch/freeze/skip, but in their player, sometimes during some of the scenes, out of nowhere, a person's face in the scene will show up as artifacts for a split second, then go back to normal. This might happen maybe 2 or 3 times through the viewing of the product. Other than that, the product plays fine in their player, no freezing or skipping, just the occasional artifacts over the face, ot the body. It has nothing to do with compression quality. The compression quality is superb, and like I said, in my own player, the product plays with NO artifacts throughout the entire movie, and we're not talking about a sophisticated player. I own an Apex AD-1200. It's just that on this one customer's player, they get the occasional artifacts. And to add to that, it's not ALL the time. With some products I sell them, the artifacts do not occur at ALL.
This person's DVD player can play +R and -R discs. If I were to switch to using + discs with this particular customer [I currently use -R's with them], would the chances of the artifacts occuring be lower? I HEAR that +'s are known for certain error correcting in the dye that makes them better than -, IF your player can play +'s. Any help/advice would be appreciated.

Since you use the LG GSA-4040B, maybe you need to read the following link and the review mentioned:

Most DVD players generally have less tolerant error correction capability compared to PC DVD drives. If you want to avoid customer complaints, then getting a burner with the best writing quality is probably more important than getting one just for personal use. Just my two cents.

Do you have any suggestions as far as such a burner is concerned?

There seems to be a general consensus among many people that both the Pioneer DVR-A06/106D and Plextor PX-708A have probably the best writing quality among the dual format burners:

This RJW fellow does know what he's talking about.

??Since you use the LG GSA-4040B,??

I suggest you also look at http://www.tomshardware.com/, they rate the LG quite well.

I possess one and all types of media work in my cheap DVD Player, everything except DVD-RAM which was not expected anyway.

Great DVD burner, perfect results on cheap media!.

Been around a lot longer than some!.
