[linux-dvb] usb-vp702x: Can't record dvb-stream

[David Fröhlich]

Hi,

I try to get an external USB DVB-S Box from Typhoon working with my linux 
server.

The USB-Box is the one from 
http://linuxtv.org/wiki/index.php/DVB_USB#TwinhanDTV_StarBox_-_DVB-S

I'm using a vanilla linux 2.6.15.5 kernel.

Here is the output of dmesg:
---------- 8< ---------- 8< ---------- 8< ---------- 8< ----------
usb 1-4: new high speed USB device using ehci_hcd and address 2

So far, everything looks good.

But I'm not able to record a dvb-stream with mplayer:
---------- 8< ---------- 8< ---------- 8< ---------- 8< ----------
dvb_tune Freq: 11953000
dvb_streaming_read, attempt N. 6 failed with errno 0 when reading 2048

bytes
dvb_streaming_read, attempt N. 1 failed with errno 0 when reading 2048

---------- >8 ---------- >8 ---------- >8 ---------- >8 ----------

Any hints?
