Hi,
(Before I start... sorry if this a bit long but hopefully someone will find
something useful here)
Software running (on PVR):
Debian 3.1
Linux kernel 2.6.19
InitNG 0.6.7
IVTV Driver 0.9.1
VDR 1.4.4 (no patches applied, compiled under 2.6.17.11)
pvr350 VDR plugin 0.0.4pre1 (with patch applied to work properly in VDR 1.4.x
from Gentoo CVS)
dvb-apps version dated 19/10/2006
Hardware being used (on PVR):
VIA EPIA M Motherboard
Hauppauge PVR-350 PCI card
Freecom DVB-T USB Stick* (25451-rev.3**, using the dvb-usb-wt220u-fc03.fw
firmware file, has the ID 14aa:0226)***
* Digital only NOT Analog/Digital Hybrid version
** The previous version had a number of 25452
*** I do note that support for this DVB-T stick has appeared recently.
----
When VDR starts up (with the DVB-T stick concerned connected and firmware
loaded), the video and audio works fine for around 60 to 90 seconds or so and
then the video freezes and the audio disappears. If I leave it alone for a
few minutes this appears in dmesg:
dvb-usb: recv bulk message failed: -110
dvb-usb: recv bulk message failed: -110
dvb-usb: bulk message failed: -110 (1/0)

dvb-usb: bulk message failed: -110 (1/0)
dvb-usb: bulk message failed: -110 (2/0)
... (goes on for a while) ...
When I change channels (after doing the above), the same messages as above
appear. To get it working again, I have to kill VDR and unplug and plug the
DVB-T stick back in and restart VDR for it to work again.
When I change channels (straight away upon VDR starting up) this appears in
dmesg:
dvb-usb: recv bulk message failed: -110
dvb-usb: recv bulk message failed: -110
dvb-usb: recv bulk message failed: -110

dvb-usb: recv bulk message failed: -110
dvb-usb: recv bulk message failed: -110
dvb-usb: recv bulk message failed: -110
... (goes on for a while) ...
VDR becomes unresponsive for around a minute or so and when it does become
(eventually) responsive again, I get video and audio again sometimes from a
couple of seconds to a couple of minutes, and the cycle repeats with video
freezing and no audio and more 'dvb-usb: recv bulk message failed: -110'
messages appearing in dmesg.
In both cases (only one or twice), -110 is replaced with -75.
When I go into the /dev/dvb directory, there's two adapters (adapter0 and
adapter1) which belong to the DVB-T stick and are registered in dmesg:
usb 4-1: new high speed USB device using ehci_hcd and address 10

I can bodge it, it works some of the time but the 'recv bulk message
failed: -110' does appear when the video freezes and the audio disappears.
This can be done by removing one of the adapter directories in /dev/dvb so
that VDR will only use one of the adapters
Is it correct that this device (Digital only not Digital/Analog hybrid) should
have two adapters? Considering I paid around £30 (which sounds cheap to me),
it just sounds a little too good to be true to me. ;)
----
To make sure it isn't a problem with VDR itself, I preformed some commands on
both adapters:
tzap -a0 -r -S "BBC ONE" > /dev/null &
ts2ps /dev/dvb/adapter0/dvr0 0 0 > /dev/video16
Video appears and audio is heard on the TV. After killing ts2ps and tzap, I
try the other adapter using the commands below:
tzap -a1 -r -S "BBC ONE" > /dev/null &
ts2ps /dev/dvb/adapter1/dvr0 0 0 > /dev/video16
Again, video appears and audio is heard on the TV (I then kill ts2ps and
tzap). However, if I tzap both adapters and use ts2ps on one of the adapters
nothing appears on the TV screen using the commands below:
tzap -a0 -r -S "BBC ONE" > /dev/null &
tzap -a1 -r -S "ITV1" > /dev/null &
ts2ps /dev/dvb/adapter0/dvr0 0 0 > /dev/video16
After killing both tzaps and ts2ps, I tzap the first one and ts2ps it
into /pvr/test/BBCONE.mpg:
tzap -a0 -r -S "BBC ONE" > /dev/null &
ts2ps /dev/dvb/adapter0/dvr0 > /pvr/test/BBCONE.mpg &
When I do ls -l twice the file size increases:
-rw-r--r-- 1 root root 2086876 2007-01-09 14:52 BBCONE.mpg
-rw-r--r-- 1 root root 3829326 2007-01-09 14:52 BBCONE.mpg
Now, when I do this:
tzap -a1 -r -S "ITV1" > /dev/null &
and do ls -l again twice the file size does not increase as it has stopped
writing since the tzap for the second adapter was started:
-rw-r--r-- 1 root root 38865603 2007-01-09 14:53 BBCONE.mpg
-rw-r--r-- 1 root root 38865603 2007-01-09 14:53 BBCONE.mpg
When I do ts2ps on the second adapter (adapter1), the data
from /dev/dvb/adapter1/dvr0 is written into /pvr/test/ITV1.mpg
ts2ps /dev/dvb/adapter1/dvr0 0 0 > /pvr/test/ITV1.mpg &
After I've killed both tzaps and ts2ps processes, I pipe the BBCONE.mpg file
into /dev/video16 and that plays fine until the point where I had entered the
second tzap command (which is where the video ends). However, when I pipe the
ITV1.mpg file into /dev/video16 nothing appears on the screen, so I transfer
the file to my PC and play it on there. What I get is a garbled picture
(picture, parts of it out of place and parts of the video frames having MPEG
artifacts on it).
In theory, if I tzap both adapters at the same time and save the data from
both, both should be writing data at the same time or am I wrong on that?
I think what's going on with VDR is that it's using the second adapter to get
EPG data but currently it doesn't work on the DVB-T stick (as it can't seem
to use two adapters at the same time) I'm using and so causes the video and
audio to stop (like the BBCONE.mpg file has).
----
Finally, if I reboot my PVR when a load of 'recv bulk message failed: -110'
messages have appeared (not switch off and turn on but reboot) leaving the
DVB-T stick in a warm state, when I log into the PVR I sometimes get a kernel
oops in dmesg like the one below (partial dmesg output follows as this message
is somewhat big enough already, please ask for full dmesg output):

This doesn't happen when I take the DVB-T stick out, reboot, and put the DVB-T
stick back in (thus putting the DVB-T stick in a cold state).
----
Anyone else having problems that I'm having? Any suggestions and ideas (any
other tests I should do?) are appreciated.
Thanks,
Steve
