u can burn truncated copies through any burner but they are incomplete 97% verified.to burn 100% verified, u need a special LT-MAX burner.some older games work on truncated method but they are not online safe.
as for L0-L1.it means the security check sectors are blank on the iso.set ur abgx to level3 and then execute it.it will fix that for ur automatically.
I haven't really tried DWN TV. My khala has it, she is satisfied but it does have its problems. Sometimes, some channels don't come and etc. Though, DWN has good quality.
Smart TV has a LOT of problems but they came for a short while, then a long period of no problems. If you have a relative in PTCL, then surely get Smart TV. The video quality is excellent.
