Features

The DVD-2500BTCI can play BD-video, DVD Video, CDs, and Kodak Picture CDs.  It can also play MP3, WMA, JPEG, and DIVX pc formats that are stored either on disc or on a SD memory card.

The 2500BTCI allows you to manually set the output resolution between 480i, 480p, 720p, 1080i, 1080p60, and 1080p24.  1080p24 works correctly if there is 1080p24 frame material on the disc, the display you are using supports the mode, and the display’s EDID reports the mode correctly to the player.  If not, the player will default to 1080p60 or the next available resolution that the display supports.  As of writing this, there is a firmware update released that addresses the selection of 1080p24 but I was unable to confirm its operation.

One of the most attractive feature sof this player is its ability to output HD audio codecs in their raw bitstream format. For someone like me who owns a dedicated AV processor, this is a preferred choice because the high quality components in the AV processor allow the sound to be reproduced exquisitely.   To enable this feature HD Audio output should be set to Normal.  If it’s set to HD Mix then the player sends the audio as a 5.1 PCM signal.  HD Mix is actually a feature used for special pip content on a BD disc.

The Blu-ray 1.1 profile requires the device to be able to play picture in picture content and as mentioned before, the 2500BTCI is capable of playing this content.  This feature is typically used for audio commentary or other novel ways of revealing more info about a film.  There haven’t been very many releases that take full advantage of this ability yet, but the recent Fox Studios sci-fi title Sunshine has it, and more will be coming on the horizon as the format develops and as more players are released that meet the hardware requirements of the 1.1 or 2.0 Blu-ray profile.  There have been reported issues with this unit attenuating the LFE content by 5db when otput through LPCM, but apparently there has been a firmware update that addresses this problem.

Standard DVD Video Processing Performance

This player is primarily designed for Blu-ray content and it, like other players built on the searlier revisions of the UniPhier chipset, didn’t fare well on Secrets benchmarks for SD content.  Here are the results.

The main issue I saw with the 2500BTCI was that it was unable to handle any of Secret’s film based cadence tests.  These high detail wedge patterns test to see if the decoder is properly handling the 3:2 cadence and this player was unable to pass any of them which effectively means that resolution can be substantially lost as the player stays in video mode the whole time.  The player is motion adaptive but it also failed the 2-2 cadence test.

On the upside, the 2500BDCI was able to display scenes with high detail content fairly well such as the Super Speedway test and also the more difficult Coliseum panning scene in Gladiator but it did take the player about a second to lock onto the pattern so I gave it a borderline score.  The DVD-2500BTCI also failed two of the benchmark tests that check for the CUE error.

Since this player doesn’t have any analog outputs, measurements weren’t taken with the Tektronix Oscilloscope.  This player didn’t crop any pixels whatsoever and a visual assessment of the YC Delay test didn’t exhibit any problems.  All in all, this player exhibits below average performance in the Secrets DVD Benchmark.
