Pioneer DVR-233S DVD Recorder
review of DVR-231-S model
I purchased a DVR-231-S, which shares the same owner's manual as the DVR-233-S, about a week ago.  I have not used it heavily so far, but here is what I have found:  the manual makes NO mention of WMA or MP3 support and I burned 5 WMA disks with different format types and brands, none of which it would play, so I do not think it plays WMA.  My One-For-All universal remote, only 6 months old, does not have the new codes for this model according to OFA support and I would have to mail it in for them to upgrade.  The first-time setup wizard is very easy and pretty fast.  The timer-recording GUI is very easy to use and allows up to 32 programs.  The recording speeds are 1,2,4,6,8,and 10 hr.  Count on having to 'finalize' your recordings before playing on any older DVD player - and be sure to use 'video mode', not 'VR', which is the default.  The 2-step on-screen display is functional, but very plain looking.  This model does not exist on Pioneer's website as far as I can tell.
