Will play discs burned from hdd but not commercial movie type dvd

The solution is simple.I rang LG service (so called - LOL)
Asked for a fix or reset method. (Which can be done but they won't tell novices how)
Got no joy, so now I will bin it,and spend the rest of my days telling people to avoid LG.
After all the posts I have since read about the same problem on various LG models,it is obvious their product sucks,they know it does, but won't accept the responsibility.
If I stop 4 people buying their ****,that's at least $1000 they miss out on.
If the process snowballs,how much then$$ ?
It would cost me $120 just to get it to and pick it up from the repair place.
Plus parts and labour added.
Before buying an LG DVD recorder go online and check out how many dissatisfied customers there are. In short, DO NOT BUY !!
