The Sherwood BD-5004 Blu-Ray player: a brief description.
My Sherwood BD-5004 arrived today. I didn't wait until Christmas to open the package.

The photographs below were taken by a hand-held Canon SD780IS and reduced in size from 4000x3000 to 800x600. The images below are thumbnails which link to the 800x600 pictures.

The box.
It's lightweight and has a plastic handle, not shown.

The contents, still in bags.
Remote, a/v cable, documents and player.
In addition to the plastic bag, the player has sheets of transparent protective plastic stuck to all of the shiny black parts of its case. The remote's two penlight batteries aren't shown. I was amused to see that their brand name was "LARGE" and that they were "extra heavy duty."

The back panel.
Captive power cord, component and composite video outs,
7.1 analog audio out, coax digital audio out,
HDMI, Ethernet and USB.
I don't know or care what kind of DACs it uses, since I'll use HDMI for audio as soon as my NR1501 comes back from getting its firmware updated. In the meantime, coax digital audio is feeding an ancient Pioneer VSX-D906S, while video is going over HDMI to the TV.
(I blanked out the serial number. It's in the low 2000s)

Powered on.
Ouch!
The lights are bright, with no way to turn them off while playing. Making an opaque cover would seem to be appropriate.
The IR sensor is just to the left of the front-panel USB connector, which is just barely visible above the buttons.
The power button (invisibly dark at the left) turns power off entirely, so the bright red standby lamp can be avoided. Since you have to go to the player to insert a disc, it's no big deal to turn it on at the same time. When powered on, the player can be put into standby using the remote.
The screenshots below were taken off the screen of a
Vizio VX240M (24" diagonal, 1080p LCD).

Power-on Sherwood logo.

Display settings.
(When playing at least some 4:3 DVDs, one must go into the service menu and change the TV Aspect to 16:9 pillarbox.)

Info.

Audio output options.
There doesn't seem to be any way to configure the HDMI output separate from the digital output.

Bass management.
Speakers can be set to large or small, with a choice of crossover frequencies for the Subwoofer. There are no distance or relative volume settings.

Title/Chapter display.
Star Trek 2009 has lots of chapters!
This one-line display format is used for all disc types, which I find disappointing. In other words, it only shows the length of the current track when playing an audio CD. I prefer to see the lengths of as many tracks as will fit on the screen.
Folder icons are shown when playing a non-audio CD. I haven't tried playing from a USB thumb-drive yet.
One can select PCM downsampling to be off, 96KHz or 48KHz. Although its internal DACs run at 96KHz, one can hope that higher bitrates are forwarded when "Bitstream HD" is selected. There's no support for HDCD decoding. I should be able to find out next week if that's bitstreamed, too.
Why I got this player.
A screenshot of a Region 2 PAL DVD. (I don't have any Region B BD discs. Yet.)
The player decodes 50Hz, 576 line DVDs
appropriately when upscaling to HD 1080p/60. Using that output format, one doesn't have to worry about the differences between NTSC and PAL video signals causing problems for the display hardware. (It supposedly can scale to 720p, too, for those with lower resolution displays. I didn't verify that.)
Mechanical aspects:
The player is very lightweight. It has no fan, so there are many slots in the sides and top for hot air to escape. Be careful not to block them. It gets vaguely warm to the touch. The drive makes high-frequency squeaks and scrapes when loading a disc, although it's very quiet when playing. Hopefully it'll last longer than its 1 year warranty.
Firmware updates:
The manual does not mention firmware updates or how one would do them. There's no obvious selection in the menu, either. Presumably the procedure will be the same as for the Momitsu BDP-899.
I currently have no plans to install Momitsu firmware: the player does what I want well enough already.
Issues:
1. It forgot the region-free configuration.
After playing several Region 2 DVDs in a row, the player stopped playing them. When a new disc was inserted, it was recognized as a DVD but the screen stayed blank.The player smelled "warm". After leaving it powered off overnight, I turned the player on, re-entered the configuration code and the same disc played fine. I dunno if this is a thermal issue (none of the vents were blocked) or something else.
2. The front panel USB connector can't be used with many USB sticks.
The hole in the plastic is too small and the plastic front panel is too thick. Although the thumb-drive's connector fits through the hole, the plastic prevents it from seating all the way: the USB connection doesn't connect. The back panel connector works fine.
3. The player sometimes generates a faint, intermittent high-pitched whistle when playing a disc.
The sound comes from within the player, not from the speakers.
