Two listed for relatively decent prices, especially since one of these listings takes best offers. Kinda curious, but certainly don't have the spare $$$ right now!
So you want me to buy one of these haha? I don't really have the $ either!

lol, you can take the plunge IF YOU DARE xD

I've got some stuff I'm listing on eBay in the upcoming days that should help out mah cash flow bigtime, I may put in an offer on one of these. Info on them is very scarce!

https://www.ebay.com/itm/Proceed-CVP2-C ... 4117298019

^ this thing looks super cool, moreso transcoder/encoder than decoder... BUT, it doubles as a swicher! Super cool concept, but I sent them various offers up to around $40 and they all got declined. They sent an offer of $264.89, and the thing's listed at $270 lol. It looks very cool, but not THAT cool!!!

https://www.ebay.com/itm/CYP-Multi-Stan ... 3988304593

^ there's this CYP (Cypress / Ambery / converters.tv / etc etc etc) that also looks kinda neat, but anyone familiar with them knows that their line of products is INCREDIBLY hit or miss, and usually moreso on the 'miss' side of things :P

Here's some pics of the VM-19N. Balrog's face doesn't look all reddish and odd, a byproduct of 'pure RGB' and RGB to YPbPr transcoders

what's your impression compared to a direct composite connection to the monitor?

Can any of these devices downscale 480i and/or 480p to 240p?

"Somewhere between composite and RGB" would best describe it, heh. Definitely more crisp than straight composite. I'm kicking myself for mailing my friend my only S-Video console cable mere days before getting this unit! I did try composite -> svid through a DVR, however, and found the difference to be extremely marginal.

Strangely, it gave me very blue/teal tones for the selection bar on the home screen on my PSIO, which normally appears as a neon green when connected via straight RGB. This color deformation isn't really noticeable in actual gameplay, however...

No scaling at all on the Kramer, nope. Fudoh's covered most every device that can downscale stuff to 240p on his website, save for a few other devices such as the DIDO JR, GBS Control, and possibly several other obscure processors out there.

https://www.ebay.com/itm/DWIN-Model-VDC ... 638990294#

This auction is about to end, thinking of taking the plunge... there's zero info available online, anyone heard of this one? The fact that it's RGBS out leads me to believe it probably doesn't scale the image, but ehhh, IDK. Dunno if it will 'outshine' the Kramer. I HAVE heard DWIN made some good stuff, but haven't heard too much about 'em overall

Can confirm that this decoder properly processes 240p :) Also provides more 'faithful' colors than the Kramer VM-19N (which I have listed on my eBay currently)

I'm selling my Kramer VM-19N, and happened to notice there's someone else on eBay selling one - they also have a Kramer FC-19, and the two units look to be EXACTLY the same. I wonder if there's much/ANY difference goin' on under the hood, and also wonder which is the older unit? My gut is telling me that the FC-19 is probably older... I would assume it is ALSO 240p-friendly (especially if it's the older of the two) since they are so near-identical.

Still tempted to take the plunge on that TrueVision Madras thingy! Looks quite interesting :)

A heads up to ldeveraux or anyone else who may be interested in that Madras device - a kind and thoughtful user here PM’d me and told me they used to own one & to avoid the thing... ‘tis apparently an absolute headache to get it to sync/work properly for any sort of casual use that most of us would try to implement it for. Bullet dodged!

You forgot the @ symbol! Yeah I don't think I was going to buy it anyway unfortunately...

Oh, does doing that actually send us notifications? Interesting! If you do end up interested in a decoder, I have a Kramer VM-19N that I could literally deliver to your stoop if you still live 2 towns away from me :P

Randomly saw one of these on eBay - anyone ever seen/owned one? ITU-R BT .656 being listed makes me think 240p may be plausible, but “totally digitally designed architecture” makes me second guess it. Those Key Digital KD-VP6 and VP8 units, they have an option for line doubling all inputs to 480p... meanwhile, this supports even higher resolutions yet does NOT do any scaling of its own. Interesting lookin’ fellas!

https://www.ebay.com/itm/202893376986
https://www.ebay.com/itm/224311623150

Two units available on eBay at the moment - could be a fun experiment trying one out RE: 240p support. Even if not, could still be fine for chaining before a OSSC, GBSC, etc :)

Also, one more interesting experiment I decided to share with you folks. NoAffinity recently helped me make some repairs to that CYP CMT-7 decoder I own (there is a switch on the back for switching between RGB and YUV output).

Spoiler: show

^ This is a screenshot via the CYP Decoder, NES composite to RGBS into the 15kHz daughterboard on my multiformat Sampo monitor

Spoiler: show

^ THIS is the same decoder, set to YUV out instead. It was then fed into a YPbPr to RGB transcoder and THEN into my monitor. The change in the colorspace is quite interesting, more saturated... reminiscent of the RGB palette from the PlayChoice 10 PPU! Unsure if perhaps the transcoder only outputs Rec. 709 and not 601...? Beats me :P It is a Key Digital KD-CTCA2
