The log shows a 1-1 match between allocations and deallocations, except
for three excess allocations about 45 lines before the end.  I have no
idea what's up with those.  They may be an artifact arising from where
you stopped copying the log data.

There are as many as 400 iTDs being allocated before any are freed.
That seems like a lot.  Are they all for the same isochronous endpoint?
What's the endpoint's period?  How often are URBs submitted?

I use 2 dvb sticks, capturing digital TV. For each stick 5 URBs on a 
single endpoint are used, I think. I'm not sure, which endpoint in which 
alternateSetting is active. I attached the output of 'lsusb -v' for the 
sticks.
How can I track down the other information you need?

Use usbmon (see Documentation/usb/usbmon.txt).
