Problem Sending Command to Sony DVD/VCR #98

This is probably more user error than an actual issue. I've been able to utilize the code to do most of what I want but there is one device that is causing me trouble. I'd appreciate any guidance and have tried to record my steps:

I downloaded the latest version IRLib2 and am using the sketch
IRLib2\examples\record.ino to capture samples of an IR Remote on an Arduino Uno. I'm using a VS1838B IR Reciever which is a 38khz receiver.

I've used this to successfully capture/replay remotes from Tivo, Apple, Roku, JVC, and even a 5 disc Sony DVD Changer. However, when I try to capture and playback a remote control command for the Sony SLV-D350 DVD/VCR unit, I can capture the device (Length 20, Protocol Sony, Value:0x58BCA), but upon playback, the unit doesn't recognize the sequence.

During capture, I get the following for a single button press of the "PLAY" button

Received Sony Value:0x58BCA
Received Sony Value:0x58BCA
Received Sony Value:0x58BCA

When I play it back (using the r key), I can verify that the IR LED is transmitting, but the device doesn't accept/respond to it:

Sent: Length 20, Protocol Sony, Value:0x58BCA

I've tried some varients including sending the command multiple times in a row (2, 3, and 4 times)
Manually passing in 40Khz as the last parameter in a single command and multiple times in a row (2, 3, and 4 times)
Commenting out the include for #include <IRLib_P02_Sony.h> so that it will record and playback just the raw data, this too does not work.

To further debug, I did upload the sketch IRLib2\examples\rawRecv.ino and captured the same keypress "PLAY" on the remote and then used the IRLib2\examples\rawSend.ino to play it back, same issue. The default playback frequency is 36KHz. I tried that and also 40KHz. In both cases the Sony DVD/VCR doesn't respond.

#define RAW_DATA_LEN 42
uint16_t rawData[RAW_DATA_LEN]={
	2290, 694, 498, 694, 1218, 602, 494, 694, 
	1222, 594, 1094, 694, 622, 602, 494, 698, 
	618, 602, 1190, 598, 622, 598, 1190, 598, 
	1198, 618, 1194, 594, 1202, 614, 594, 598, 
	606, 614, 1194, 598, 494, 722, 1194, 594, 
	498, 1000};

Finally, here's the output using Hash Decode (IRLib2\examples\hashDecode.ino) with a small tweak to set myDecoder.dumpResults(true):

Ready to receive IR signals

Space min:550	 max:650

I don't have any IR Debugging tools besides this and have done some additional reading in the manual.

Any advice or guidance on what should be my next steps?

Thanks!
