Pioneer DVR-A07XLA - How to burn DVD at 1X

Hi, I know others might ask why burn at 1X. Well, my stand-alone DVD player could not seem to read DVDs burned at 2X and higher well. The DVDs will play find then at certain portions, they will stutter or just stop. I wanted to test burning at 1X to find out. If it still could not read DVDs burned at 1X well, I might try changing brand or time to buy a new stand-alone DVD player.

So my question is how can I burn at 1X. Ulead DVD MovieFactory 3 shows speed options of maximum and 2X only. Nero only shows speed at Maximum, no other choices.

Thanks for any advice.
