[linux-dvb] Modules for Nova-T - general modules question as well

["Mark Howells" <Mark.Howells@softoption.com>]

I'm confused about which modules I need to load for for Nova-T (using kernel 2.4.25). I'm also confused about which modules do what.

I have a number of queries and one error.

1. Once I've loaded the modules, what entries should I see in /dev/dvb/adapter0? I currently see
    demux0
    dvr0
    frontend0
    net0

But I've seen many docs (eg http://www.ethics-gradient.net/myth/mythdvb.html) describing the Nova-T as supporting 
    crw-rw-rw- 1 root root 250, 1 May 8 22:25 audio0
    crw-rw-rw- 1 root root 250, 6 May 8 22:25 ca0
    crw-rw-rw- 1 root root 250, 4 May 8 22:25 demux0
    crw-rw-rw- 1 root root 250, 5 May 8 22:25 dvr0
    crw-rw-rw- 1 root root 250, 3 May 8 22:25 frontend0
    crw-rw-rw- 1 root root 250, 7 May 8 22:25 net0
    crw-rw-rw- 1 root root 250, 8 May 8 22:25 osd0
    crw-rw-rw- 1 root root 250, 0 May 8 22:25 video0

Here's what I am currently loading (or trying to load)
    modprobe input
    modprobe evdev
    modprobe videodev
    insmod ./v4l1-compat.o
    insmod ./v4l2-common.o
    insmod ./video-buf.o
    insmod ./dvb-core.o
    insmod ./ves1820.o
    insmod ./tda1004x.o
    insmod ./grundig_29504-401.o
    insmod ./saa7146.o
    insmod ./saa7146_vv.o
    insmod ./ttpci-eeprom.o
    insmod ./dvb-ttpci.o ### FAILS
    insmod ./dvb-ttpci-budget.o ### FAILS
    insmod ./dvb-ttpci-budget-av.o ### FAILS
    insmod ./dvb-ttpci-budget-ci.o

So, two issues. Firstly, I believe the dvb-ttpci* modules should be loaded but they generate the following error

    Inserting DVB modules into kernel./dvb-ttpci.o: init_module: No such device
    Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.
    You may find more information in syslog or the output from dmesg

And dmesg generates
    Linux video capture interface: v1.00
    saa7146: register extension 'dvb'.
    saa7146: register extension 'budget dvb'.
    saa7146: register extension 'budget_ci dvb'.
    saa7146_core: found saa7146 @ mem de966000 (revision 1, irq 10) (0x13c2,0x1011).
    DVB: registering new adapter (TT-Budget/WinTV-NOVA-T PCI).
    tda1004x: Detected Philips TDA10045H.
    tda1004x: Detected Philips TD1316 tuner.
    DVB: registering frontend 0:0 (Philips TDA10045H)...
    TT-Budget/WinTV-NOVA-T PCI adapter 0 has MAC addr = 00:d0:5c:23:e6:43
    saa7146: register extension 'budget dvb /w video in'.

Presumably there's something missing from the kernel to prevent the dvb-ttpci* modules from loading, but I can't for the life of me find out what it is.

And secondly, I do appear to need the ves1820.o module. I wasn't aware that this was associated with the Nova-T.

The card works - the scan and tzap and dvbstream utils work, but mythtv doesn't seem to like it as it is unable to read any video data from the card - I don't have access to the machine at the moment to provide details of what goes wrong.

Any help concerning the above would be appreciated. Also, a 'Beginners Module Guide' would be useful to help new users get started - I'm happy to try and draw one up if I can get my head around what's going on!

Cheers

Mark
