The H4000 hooked to my HD-ready 29" Philips CRT TV
which notably lacks HDMI inputs, so HD over Component
is the only way. To my knowledge the H4000 is the ONLY
DVD player capable of bypassing HDCP and doing HD over CVI.
Are there things that could be improved?
Yes. If you plan to use it for mp3 playback or if you have audio in .ogg (Vorbis) format, or if you plan to look at high-quality (2MP and upwards) photos with this player, be advised that these features leave a lot to be desired.
For instance, photos look as if they are reduced to 640x480 then displayed (with visible dithering). MP3 and general data cd-r or dvd-r file browsing is limited because it doesn't support long filenames (Joliet). The names are shortened to the first few characters.
That's why I'm waiting to see if they fix these issues via a firmware update.
However, if all you want is a DVD player that does HD 1080i or 1080p upscaling via component video outputs, this is a must, get one while you can!.
