Re: video from USB DVB-T get damaged after some time (it9135)

[kapetr@mizera.cz]

Hello,

== Antti:

May I ask, if you have the same one stick?
Does it work without problems ?

== everybody:

I have final tested it under W-XP SP2 with orig drivers and SW.
It goes into problems after some time too, BUT there is a difference: It 
is able to "recover" from it itself and it plays again (for some time).

As I wrote - it happens quicker and more frequently on TV channels with 
lower/worse signal. That is why I thing that tuner will lose "tuned" 
status to exact freq.
Would be not possible to solve this (to re-tune) in driver ? It seems, 
that in W-XP is something like that in drivers.


Regards
