Making it Work

Firmware

is there any firmware specific information for this card? if so, list it here ... this means you

Drivers

There are currently no in kernel drivers for this card.

If someone wants to provide a brief synopsis of the driver tail of woe, outlining why there isn't a greater level of support, then do so here ... this means you

However, experimental support does exist.

provide the details of where the drivers and patches and necessary tools are available ... this means you ... you can use the following older content from the article as a basis for your write up:

( Method 1) Twinhan provides a tarball containing a v4l-dvb linux driver and a version of dvb-apps on their website: http://www.twinhan.com/download_driver&software.asp

It uses an ioctl to switch between DVB-S and DVB-S2 modes. An application to do this called 'switch' is supplied.

Multiproto is not required.

provide details of how to compile for recent kernels -- this means you

(Method 2) A current solution is based on the multiproto and mantis trees from http://jusst.de/hg/. However these have not yet been merged into mainstream v4l-dvb, and unfortunately as of Jan 2008 the author of multiproto seems to be willing to block this process indefinitely.

Kernel 2.6.20 works ok.

Obtain multiproto: hg clone http://jusst.de/hg/multiproto

Use following patch to patch multiproto http://pansy.at/gernot/twinhan-vp1041-3.diff.gz

Compile the patched multiproto and install.

Obtain scan from http://jusst.de/manu/scan.tar.bz2 and slot in the util/scan directory of hg http://linuxtv.org/hg/dvb-apps/. Fix up the .h includes to come from the earlier multiproto compilation.

Obtain szap.c from http://abraham.manu.googlepages.com/szap.c and compile it in util/szap according to http://www.linuxtv.org/pipermail/linux-dvb/2007-October/021474.html

Sample kernel output

provide the relevant portion of dmesg here

Tuner / DiSEqC / Player support

provide details of how to use with VDR, MythTV and Kaffeine here -- this means you

Use scan to create a channels.conf. Then to tune to a channel do:

szap -r -p -i -a 0 -l UNIVERSAL -t 0 -c channels.conf "channelname"

and then

mplayer - < /dev/dvb/adapter0/dvr0

(assuming the card is your adapter number 0)

Without the interactive -i option szap tunes and locks but is unkillable (with ctrl-c or kill) to change to another channel. Interactively type channel names in the terminal to tune to each one.

Without the -p option DVB-S2 streams are not playable.
