I am not saying this makes it okay for a product to be released with defects, but just explaining how it can happen without any sinister underlying reason.
After pages of discussion focused in on the two main issues of power-on and 23.976 judder, I would invite the readers to take a step back and look at the bigger picture - which is that the EP950 is overall a good player receiving support and updates. Our goal is to resolve the power-on and judder issues, and hopefully that will make it a great player. We understand that not everyone who buy a EP950 will decide to keep it - this is why we work with Amazon.com to sell this product, because they offer an easy no-cost return process.
Quite a bit of the content people want to play is 23.976fps. There is no way to play this at the exactly correct frame rate on the ep950 at this time.The EP950 FAILS to play the correct frame rate.
In talking with more than one specialist on digital video, they state it is ill-conceived to play back video at a different rate than indicated by the content, unless there is substantial additional and usually unnecessary processing.
The descriptions offered in Jack@Micca's post above, that EP950 is "complex," and a "good player" are entirely subjective.
Let's leave out the self serving subjectivity for a moment and focus on the problem that the lack of correct playback at 23.976 is a long standing issue for Realtek chip based players, causing non-smooth playback.
This is a failure to inter-operate properly with content.
The content file at 23.976fps complies with the standard for conveying the playback frame rate to the player. Realtek 1186 based players ignore this information and play the files at an arbitrary selected rate of 24fps.
The output frame rate of player should be time locked, in sync with the source material. The EP950 does something else.
EP950 is Complex? Yes!
- but lots of players do it correctly.
EP950 is Compliant? - No!
- it playes video at arbitrary frame rates causing incorrectly repeated frames and / or dropped frames. The content doesn't have these repeated frames. It is the failure to play at the correct frame rate by the EP950 that causes the issue.
EP950 is Good? - Irrelevant and subjective.
Please refer to the the issue at hand. The EP950 plays at non-compliant
Will vendors of players using Realtec 1186 chips start telling the facts in their literature, that these players do not play content at the correct frame rate?
Has Realtec ever admitted to this issue?
Has Realtec promised to support their vendors and customers with either improved firmware or a new player chip that will play back files correctly?
Is there any chance they will support AVCHD 2.0 3D playback for my Sony 3D TD10 camcorder files, for which I provided test files several months ago?
