I put a CDRW into my drive and I get: "To view the contents of this disc, you must install Sonic UDF reader.  Would you like to download Sonic UDF Reader now?"  Bad news.  Stop using Roxio, people!

The program attempts to download the software - and fails miserably.  So then I run a Google search - turned up a few links on www.roxio.com - except, it seems you have to "register" to get to the download page!

This file is for users that do not own a copy of Easy CD Creator and just want to read discs that have been written in UDF. 
The UDF Reader (version 5.1.1.213) is included with DirectCD 5.1, so if you have Easy CD Creator Platinum 5.1 or Basic version 5.11 or later you do not need to download this file.

Enables some MultiRead CD-ROM drives to read UDF formatted CD-RW discs (such as those written with DirectCD) under Windows 95, 98 and 98 SE, Windows NT 4.0 SP3 or higher and Windows 2000/XP.

Once installed, you do not need to take any special steps to activate the UDF Reader; it is constantly active in the background, waiting for you to mount a UDF disc. This is a free download for the convenience of users who do not own Easy CD Creator. However, Roxio only provides technical support for the UDF Reader if you purchased Easy CD Creator, and have a valid Tech Support ID (TSID) that came with the product. If you do not have Easy CD Creator, we do not provide technical support for this product.

Too bad this link is COMPLETELY and UTTERLY useless if you do not own the product already!

I'm not going to bother attempting to find a hacked version, or some random link somewhere.  I'm just going to declare this disc as "unreadable".  What a joke.  It took me 15 minutes to look on their site, and 4 minutes to make this blog entry.  Go figure.  My data is still unreadable.

(Sorry about the JPEGed screenshot - I saved it as the wrong file by accident.)

Roxio makes you login to download free software - but to login/register, you need to own a Roxio product.  Whoops!
