Things look good...  Now you should download dvb-apps from cvs:

(soon to be featured on a howto near you...)

1) get the test applications:
cvs -d :pserver:anonymous at cvs.linuxtv.org:/cvs/linuxtv login
(use an empty password)
cvs -z3 -d :pserver:anonymous at cvs.linuxtv.org:/cvs/linuxtv co -P dvb-apps

2) cd dvb-apps && make
(dont worry about any errors)

3) create a directory for the channels.conf file...
mkdir ~/.azap

4) scan for channels:
cd util/scan
./atscscan -A 3 -vvv atsc/us-NY-TWC-NYC > ~/.azap/channels.conf

(I use the New York City Time Warner Cable scan file -- you should
replace this as you see fit ... -A 3 will scan both cable and OTA, -A
1 only OTA, -A 2 only cable)

5) tune a channel:
cd ../szap
./azap WABC_HD -r
( replace WABC_HD with the channel name ... -r is very important)

6) decode the stream:
mplayer /dev/dvb/adapter0/dvr0 -cache 8192 -framedrop

(play around with the mplayer parameters... I use the above for force
the audio and video to stay in sync, on slower machines)


if you don't have mplayer handy, you should be able to do the following instead:

cat /dev/dvb/adapter0/dvr0 > testfile.mpeg

...and then open the testfile.mpeg in your favorite mpeg viewer, like xine, etc.

....There, I finally typed all that out... Now I will cut&paste from
here to create the new howto page... :-D

Hope this helps,

Michael Krufky
