I wanted to know if there was a difference between burning ISO file and DVD Video files. I have read it but I wanted to share my experience.

So I've burned a couple of Ritek G04 with two different burners

Test set-up
Riteks were burned with the following writers:
Pioneer 108 f/w 1.14
NU DDW-082 f/w B377
Software used:
DVD-Decrypter 3.5.1.0
Nero burning rom 6.3.1.17
Test: Nero CD-DVD speed 3.21 (quality test)
Tested with the NU at 4x speed

Conclusion
Lower PI/PIF when burning with ISO file.
Best results was with Nero - Iso file but not by much.
The NU looks bad, bad and terribly bad, but it really showed that ISO file
burning is better.
btw, does anybody knows what "Glitches removed" mean?
