I deleted the post that was here and I now replace it with: Grrr! I managed to get the wrong frequency analysis to look at, the one of the "right" file. It's still broken. If you read my previous post, please ignore where I say it got fixed.

The IRQL_ error sounds a lot like something to do with USB. The only thing in all of this that needs to know anything about IRQ levels is the device driver. However there's nothing very special about the USB driver for the device, I had mine talking to SonicRage quite early on, and the driver is pretty generic at the computer. I note that Sony specifically say that you cannot connect a MD player via a USB hub to the computer - could this be the problem?

You could try installing Windows on Innotek's VirtualBox software. It works quite nicely under Linux. Cheers

Hi folks. Please feel free to correct me, if I got it wrong. I want to be wrong!! I am the proud owner of a brand new MZ-RH1 (and a good pair of ears). I was busy uploading all sorts of stuff from MD's to my computer when I noticed that the sound was unusually flat, dull and lifeless. Let me give a little bit of background - until now I have been recording via the analog input of a JE 5xx or 6xx deck from my stereo system, then walking the MD to another deck in my computer room, and playing back the optical output into the digital input of my sound card. This works perfectly but it's a bit slow - I have to play through the music (at least) twice. The advantage is I can use a wave editor easily before burning the results to CD. I love the sound I get, and eventually I will be able to retire all my old equipment. So I thought perhaps "eventually" might become "soon" if I could do fast uploads using the new technology in the MZ-RH1. Back to the results of my uploading. I took the first 20 seconds of a recording that I made using the old method, and frequency-analysed it using CoolEdit (now Adobe Audition). The music source is a Rachmaninov Piano Concerto - piano music with orchestra is probably one of the best things for testing listenable sound. The result is shown in the first attached graphic. Then I repeated the procedure with the USB upload from my new MZ-RH1. The result is dramatic. There is a loss of high frequency so bad that on the default setting of the wave display (0 to -120dB) there is nothing showing above 16 kHz. I expanded the scale to -160dB just to show that it is apparently still there but hugely attenuated. Please can anyone try to confirm this? Is there anything I can do? NOTE: I also tried changing the upload setting in SonicStage to "PCM-1411Khz" and the result appears to be unchanged. Thanks to all you MD experts for your advice on this. I am getting a bit ticked at Sony - it looks like they convert the "NetMD" tracks before uploading them and the conversion kills the sound. I haven't yet tried recording from HiMD as I don't yet have an optical cable to plug INTO the MZ-RH1 as a source of "good" sound, and of course I cannot record Hi-MD's with a JE630.
