The reliability of Sony electronics is poor. I would recommend this product, especially if...  I am using the player in conjunction with a Sony TV and sound system. It works great.
Ernster 4:47am on Tuesday, August 17th, 2010 
This is my first blu-ray player. It works perfectly and my daughter loves the Disney movies that came with it. It is an excellent deal. Got the unit, updated the firmware, plugged it in, and changed a few of the audio and video settings to fit my preferences. Bad idea.
wjhoffman 4:19pm on Sunday, July 4th, 2010 
very good value great price; small footprint; good picture on both blu-ray and standard dvds; remote also works on non-Sony tv; plugged into router a... Looks great when it works, it truly is a Blu Ray player, just not a very good one considering the price. Looks.

Got it from Bydig for 127 - you may see much better deal in 2010.I have Sony BDP-BX2 from Costco and it came with backlit remote and HDMI cable. Was a Christmas present and the person the gift was for saw it on the porch with pictures of what it was.

Great deal for the price. If you need a basic Blu-ray player then you have it right here. Newegg service and shipping is the best around, as always.

unhelpful audio settings A great player overall, and I think it does an excellent job of upscaling. Not the fastest load time but not unbearably slow.

Note on video component hookups
You can connect your TVs audio output jacks to the VIDEO 2 AUDIO IN jacks on the receiver and apply sound effects to the audio from the TV. In this case, do not connect the TVs video output jack to the VIDEO 2 VIDEO IN jack on the receiver. If you are connecting a separate TV tuner (or satellite tuner), connect both the audio and video output jacks to the receiver as shown above.
Digital component hookups
Connect the digital output jacks of your DVD player and satellite tuner (etc.) to the receivers digital input jacks to bring the multi channel surround sound of a movie theater into your home. To fully enjoy multi channel surround sound, five speakers (two front speakers, two surround speakers, and a center speaker) and a sub woofer are required. You can also connect an LD player with an RF OUT jack via an RF demodulator, like the Sony MOD-RF1 (not supplied).
You cannot connect an LD players DOLBY DIGITAL RF OUT jack directly to this units digital input jacks. You must first convert the RF signal to either an optical or coaxial digital signal. For details, see Troubleshooting on page 50. All the OPTICAL and COAXIAL jacks are compatible with 96 kHz, 48 kHz, 44.1 kHz and 32 kHz sampling frequencies.

Multi channel input hookups

HT-DDW840 only

Although this receiver incorporates a multi channel decoder, it is also equipped with multi channel input jacks. These connections allow you to enjoy multi channel software encoded in formats other than Dolby Digital and DTS. If your DVD player is equipped with multi channel output jacks, you can connect them directly to the receiver to enjoy the sound of the DVD players multi channel decoder. Alternatively, the multi channel input jacks can be used to connect an external multi channel decoder. To fully enjoy multi channel surround sound, five speakers (two front speakers, two surround speakers, and a center speaker) and a sub woofer are required. Refer to the operating instructions supplied with your DVD player, multi channel decoder, etc., for details on the multi channel hookups.

x Center speaker size (

If you connect a large speaker that will effectively reproduce bass frequencies, select LARGE. Normally, select LARGE. However, if the front speakers are set to SMALL, you cannot set the center speaker to LARGE. If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select SMALL to activate the bass redirection circuitry and output the center channel bass frequencies from the front speakers (if set to LARGE) or sub woofer.*1 If you do not connect a center speaker, select NO. The sound of the center channel will be output from the front speakers.*2 x Surround speaker size (
Internally, the LARGE and SMALL settings for each speaker determine whether or not the internal sound processor will cut the bass signal from that channel. When the bass is cut from a channel, the bass redirection circuitry sends the corresponding bass frequencies to the sub woofer or other LARGE speakers. However, since bass sounds have a certain amount of directionality, it is best not to cut them, if possible. Therefore, even when using small speakers, you can set them to LARGE if you want to output the bass frequencies from that speaker. On the other hand, if you are using a large speaker, but prefer not to have bass frequencies output from that speaker, set it to SMALL. If the overall sound level is lower than you prefer, set all speakers to LARGE. If there is not enough bass, you can use the BASS +/ to boost the bass levels. To adjust the bass, see page 30.

x Sub woofer selection (

If you connect large speakers that will effectively reproduce bass frequencies, select LARGE. Normally, select LARGE. However, if the front speakers are set to SMALL, you cannot set the surround speakers to LARGE. If the sound is distorted, or you feel a lack of surround effects when using multi channel surround sound, select SMALL to activate the bass redirection circuitry and output the surround channel bass frequencies from the sub woofer or other LARGE speakers. If you do not connect surround speakers, select NO.*3
If you connect a sub woofer, select YES. If you do not connect a sub woofer, select NO. This activates the bass redirection circuitry and outputs the LFE signals from other speakers. continued

Enjoying stereo sound in multi channel (Dolby Pro Logic )

(HT-DDW840 only)

The receiver lets you apply the last selected sound field to a program source whenever it is selected (Sound Field Link). For example, if you listen to CD with JAZZ as the sound field, change to a different program source, then return to CD, JAZZ will be applied again. You can identify the encoding format of program sofware by looking at its packaging. Dolby Digital discs are labeled with the logo, and Dolby Surround encoded programs are labeled with the logo. When sound signals with a sampling frequency of 96 kHz are input, the sound signals are output in stereo automatically, and the sound field is turned off.
The receiver can reproduce the stereo sound in multi channel through Dolby Pro Logic. You can activate the decoder using the SET UP menu. For details, see page 37.
Using only the front speakers (2 Channel Stereo)

Press 2CH.

2CH ST. appears in the display. This mode outputs the sound from the front left and right speakers only. Standard 2 channel (stereo) sources completely bypass the sound field processing. Multi channel surround formats are downmixed to 2 channel.
No sound is output from the sub woofer when 2CH ST. is selected. To listen to 2 channel (stereo) sources using the front left and right speakers and a sub woofer, press A.DEC to select AUTO DEC. When you select Micro Satellite Speaker (page 16), internal sound processor will automatically redirect bass sound to subwoofer. If you want to listen to two channel (stereo) sources under this setting, we recommend that you choose AUTO DEC. mode so that you can take advantage of your subwoofer to obtain the correct bass signal.
