Hi all,
after seeing that Zaapa is not supported and having some
troubles with an AverMedia Volar (which wasn't able to find any
channel using the roof antenna, only with the portable antenna -
[curious, the Zaapa one worked just the reverse way]), I've been able
to get a Freecom dvb usb stick.
Things went ok (nice!) at first: downloaded the firmware,
compiled & installed code from Mercurial, plug the stick and it's
recognized.
After that, used scandvb to create channels.conf, OK.
I've been able to watch TV using MPlayer with that
channels.conf file, great.
It works OK, but after sometime (maybe one hour, but is not
deterministic), everything goes bad: image starts to goes
slowmotion/frozen/pixelated, sound gets crappy, with lot of whistles
(of course, audio and video are not synchronized at that point), and I
have to close mplayer and start again.
At this point, the degradation occurs before, just one or two
minutes after the second mplayer starts running. At that point, It
cannot be solved just restarting mplayer (neither removing/reinserting
the dvb stick).
What I've tried is to remove the stick, rmmod dvb_usb_dtt200u
and start again, and it seems to work (I mean, it seems I can get an
hour of tv..), but after some time all the problems start again. I've
noticed, before the first rmmod, that dvb_usb_dtt200u was reported to
be used by 4294967293 times (see lsmod output below) :-/ Usually, that
number is 4/5 in my case (at the time of writing this, I've not been
able to reproduce it, now -regarding that it's not working-, keeps the
usage count at 4)
Trying to remove "mplayer" from the equation, I've tried to do
a test just with stream recording using tzap/cat and generating an
mpeg file, and it seems to be the same. Playing it with mplayer shows
up that the problem is in the mpeg data, not in mplayer.
Is it possible that the driver/frontend has some bug that
causes that time/use malfunction?
I'll be glad to help if I can. Below comes some information:

Too many video packets in the buffer: (433 in 8428292 bytes).
Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.
I don't have idea of what other data can I send to help, but if
it's needed, just let me know.
best,
Jose
