 The other thing to note is that this device delivers a full
 unfiltered Transport Stream, which with the 13,27Mbit/sec typical
 bandwidth per channel used in your country (apart from some local
 exceptions of greater values), will require a USB2 interface.
it is a USB2 interface:
[3.965425] usb 1-3.1: new high speed USB device using ehci_hcd and
address 6 (it's the USB hub in the box)

I also thought the USB chipset could be the problem and testet it with
an extra USB2 card.

 around line 620 in my reference code, there is a line that sets
 the alternate interface to 6.  This is expected to be bulk, but
 on my boxes is isoc.
 
 You can change this to interface 0, on which my boxes delivers
 bulk data flawlessly.
I think isoc would be okay on 2.6.32, so no need to change that, right?

 but when
 I have my machine operating fully again (yeahright), I can send
 you some of these alternative patches to try -- running 
 successfully on 2.6.14 and 2.6.27-rc4.
That would be nice.

P.S. my english is not the best so I don't understand all you wrote but
why don't you put the patches upstream?

  Or, the thing is, Linux is expecting to be seeing bulk data on
  this particular alternate interface (6).  If the receiver is not
  delivering this, but is instead delivering isochronous data, it's
  not in the same format and isn't properly handled by the driver.
 
  Changing it so that the driver reads from alternate interface 0
  results in all my hacked versions being able to read the data
  properly.  Even before reading isoc data through hubs was fixed
  sometime around or before 2.6.18-ish.
und diese verwechslung verursacht die bild-/tonfehler?

and this confusion causes the image/sound issues?

  Hast Du die 2.6.32 Quellkode?  Kannst Du aus `patches' etwas
  schaffen, und dabei die beide Moeglichkeiten testen?
 
  (Are you able to build a new kernel to test my patches to see
  if they solve your problem?)

Ja habe ich. Leichte patch anpassungen bekomme ich meist auchnoch hin.
Wirklich programmieren kann ich aber nicht.

Yes I have. I have little skills in patch adjustments (very little). But
I'm not a developer so I have no coding skills.

Vielen Dank im vorraus für deine Hilfe.
Thank you in advance for your help.

P.S. a few words in my text are google translated  ;)

Great job, it works!

Thank you so much :)
Should we try the isoc transfer now?

Bad image quality with Medion MD 95700

2009-12-24 Thread TAXI
Hi,
I tried a Medion MD 95700 with kernel 2.6.32 (for tests: 2.6.30.9) and
have a very bad image and sound quality.
Right now I'm using 2.6.32 with V4L/DVB from SVN (v4l-dvb-4506e2d54126)

Here is an example: http://img200.imageshack.us/img200/3950/dvbtlinux.png
and another: http://img130.imageshack.us/img130/6278/dvbt2.png

The DVB-T stream seems to be good:

(it's a bit bad right now, normally the signal is around 50%)

under windows XP the image and sound is perfect.
