Try burning the ISO at the lowest speed.

TechLore Blog

HR10-250, Samsung SIR-S4120R, SIR-S4080R, 2 Philips DSR704s (one connected to a Slingbox A/V). One box used the "Zipper"; rest used PTVnet to enable networking features.

Never mind

This is not the place for this question but I cannot find the proper place after searching.

I have HR10-250, upgraded to 6.3a, upgraded tivowebplus to 1.31, have tyserver installed and working.  My system has worked flawlessly for the past 60 days.  Yesterday, I noticed a message saying I needed to activate my DVR service.  I also now cannot watch pay per view.  I tried making a fake call and it appeared to work.  Next, plugged in the phone cord and tried to make a test call.  I tried next to get the number to call by entering my area code.  The call  always fails even though I can see/hear it making the call and says, the line is busy or in use. 

any help appreciated.  I think I need to reactivate my service with DTV somehow but not sure what to do.

Hello,

I have emailed you before regarding not being able to boot from the InstantCake CD. At that time I suggested you add the fact that the InstantCake software downloaded off your site MUST be created as an 'ISO' file (NOT a 'Bootable Image' file as you write in your Release Notes) from Nero or a reputable CD/DVD writing utility. I confirmed my suggestion to you by creating two InstantCake CDs: One as a 'Bootable Image' from Nero and the second as an 'ISO Mode1' image from Nero.
Result: The 'Bootable Image' CD did NOT boot up as a Linux image but resulted in a "[DR-DOS] A:\> " prompt. The 'ISO' image CD did boot up as a Linux image and allowed me to "Bake the Cake" and thus create a new TiVo harddrive.

Your response to me was that if the problem of not being able to boot from the CD as a 'Bootable Image' becomes a trend then you would update your Release Notes. However, I am telling you that the problem of not being able to boot from InstantCake saved as a 'Bootable Image' has already become a trend (Just check out dvrplayground.com).

Bottom Line: Please update your Release Notes. Your customers are wasting CDs by following your instructions and I contend that the issue is a trend and is not isolated.

BTW: I am posting this reply on dvrplayground.com under the following discussion threads:

Boot CDROM now boots

Thank you,

nlkirchn said: I have downloaded the Instantcake file and burned it to 3 different brands of media and cannot get it to boot.  I have checked and double checked the configuration of the drives and the PC and I still get the "operating system not found " message.  It does boot my Windows XP Professional install disk so I believe my setup is correct.  Any suggetsions?  Would the OS load from a USB memory drive?

Sounds like you are not burning it correctly.  Please document, step by step, exactly what you are doing with the file once it is downloaded, that may help refine the problem...

I finally have success. The secret is to burn the ISO file as an image not a file.  To burn as an image you have to have a full version of NERO and not use Nero Express because that option is not available.  I downloaded the trial version and burned a new disc and the disc booted immediately.  The instructions need to be more clear on burning the disc especially for a novice.
