I haven’t been playing around with FE/TE tests for very long, only 3 weeks actually. :o
I think I found a real correlation with the final quality but I’m not 100% sure yet. So don’t quote me on that.
Many folks on this site consider that FE/TE tests are rather worthless because they can get good-looking scans from burns at a faster speed than FE/TE testing indicates.
I think that one of the reasons why, is the widespread “standard scanning speed” (4X for LiteOn, 8X for Benq, 5X for NEC etc…) motto, that I personally never followed (except when needed - for the CDFreaks forum ). I scan everything @12X, sometimes even @16X, because I’m not very interested in comparing my scans with scans produced by other users. Call me a heretic. -
I consider that scanning at higher speeds helps in sorting media, quality-wise: I noticed that while some discs will show almost identical BLER figures in scans at “standard” speeds and in scans at higher speeds, some discs will show much higher PIE (and sometimes PIF) levels near the end of the disc. I like to think that these discs showing no increase in BLER near the end at higher scanning speeds are either better discs to start with (mechanical characteristics etc…), or have a better overall burning quality. This explaining why I prefer to choose discs and burning methods that give good results in high speed scans, rather than going for the best values at “standard” scanning speeds. It’s my choice, and I’m not evangelising. (though a good friend of mine adopted this method and is very happy with it).
Well to the point (at last - but the above introduction was necessary ): I think I found a significant correlation between those discs showing lesser scans at high speeds (but good scans at “standard” speeds) and the FE/TE test results. I’ll have to experiment some more to see if following the FE/TE test advice in terms of burning speed will constantly give burns that pass my high-speed scanning testing. It will need much time (I don’t believe in theories based on a limited number of cases) so don’t expect any definitive comment from me anytime soon.
You’'ve probably guessed by now that I agree with [B]DrageMester[/B]'s opinion that poor FE/TE tests can indicate a problem with the media.
Now, there is no proof that for real-world use, any of this has any relevance. I’m a DVD Freak. The vast majority of discs showing excellent PIE/PIF values at “standard” scanning speeds should have no problem in real-world use (assuming one doesn’t rely on a single scanning drive, though - if so, bad surprises can always pop up - [B]DrageMester[/B] will certainly not contradict me on this one ).
