Hi!

I looked through the patch and tested it a bit. It seems that it does 
not function like it should. For example, from time to time the download 
status was something like:
"Retrieved blah-blah, at speed 0b/s, >40000d 60h ... remaining".
This is kinda crazy :-)

I modified the check there a bit to
if (CurrentCPS > 0.1 && ...)

that helped, but not that much, still from time to time I received 
messages like:
"Retrieved blah-blah, at speed 0b/s, 6s ... remaining".

That's much better of course, but still a bit crazy as download speed 
from CD-ROM is surely higher than 0b/s :-)

Are there any means to remove those speed and time estimates from the 
fetch dialog in case packages are downloaded from a CD-ROM? Of course in 
case of mixed downloads (e.g. from both CD and web) this info should be 
displayed from time to time...

BTW, the best solution would be if apt/synaptic would find the download 
speed of a CD-ROM and count correct time estimates. Downloading a 50MB 
package does take some seconds, but during this time the progress is set 
to 100% and speed is still 0. Or is it technically impossible?

Thanks,

Andrey
