The upgrade process isn't complicated; just read the documentation on the web site and follow the directions. If users don't know how to burn an image with their particular sort of cd burning software; then this is really not a Plextor issue, but a use of software issue. The problem is, there are numerous brands of cd burning software, and Plextor (I can't imagine this to be the case) cannnot be responsible for teaching people how to do this; this list can help with such issues. Personally, I like:
$ cdrecord dev=0,0 speed=16 -data PTR1VERUP200ENG.iso
but it's all up to the user.
As for the documentation; maybe the manual isn't just the thing for everyone, but if one actually reads it, or searches for the sections relevant to what you're trying to do; it has all the information in it; I had no questions about the use of the machine after reading the whole thing. That's not to say refreshing of my memory wasn't needed, because there was so much information there, but you learn how to do some basic things with the machine, and when you've mastered that, learn the more complicated things through the use of the manual, this list, and experimentation. There is documentation on the ptr1 site, about the new features in V2, and how to upgrade; I followed those instructions and it happened...
There may be an issue with some stray RF on the case of the PTR1, but this isn't unusual in the case of almost all devices that have a power supply, especially if the case of that equipment isn't grounded through a separate line (the safety ground) which I believe all computers have. The PTR1's power supply has a two-conductor cord and uses a switching power supply (down to 10V DC 2.5A) and has to be well isolated for safety reasons. The fact that the computer is grounded and the PTR1 is not, might well mean that when a user makes a connection between the two devices, there could be a small low voltage difference between them. This is a common problem and I've experienced it many times with a wide variety of equipment.
As for the audio hum when recording. My solution is to either: * Reverse the plug,
* Try a different mic, or if the input setup is more sophisticated different connecting cords,
* My favorite: wind a few turns of the cord from the input device through a ferrite bead (toroid or tube).
Success with the above three suggestions varies depending upon numerous external conditions, use, ETC.
