Hi.
I'm looking at getting the following from dvbshop.net
Technotrend Remotecontrol SET Technotrend Technotrend "Dual Tuner" Package (Technotrend Premium S2300 (Rev 2.3) "modded") RGB/S-Video J2 Extension for Technotrend Premium (for component/RGB-out)
Has anyone got any advice on getting this working with VDR?
I've been using VDR with budget cards for a few years with vdr-xine. This will be my first FF with an MPEG decoder - any problems/advice on the quality of the RGB-out?

That card works fine, in fact its recommended by many vdr users. Here is the scoop.
The card does NOT do HDTV decoding in hardware. It will do it in software assuming the modulation is QPSK, (it does NOT support 8PSK commonly used for HDTV at least here) The card is used like a budget card if you are doing HDTV.
The "j2" mod on that board is done incorrectly. It does NOT have the proper circuitry to work "out of the box", (It does NOT do component, only RGB). It is NOT terminated properly. It does post a risk of damaging the card if things are incorrectly wired. Correctly wired and terminated the RGB out works excellent.
Any other questions?

I'm confused. I thought component video was RGB? s-video uses luminance and chrominance, component uses RGB - am I wrong? The SCART pinout says "RED/Chroma pin 15", "RED/Chroma GND pin 13", "Green pin 11", "Green GND pin 9", "Blue pin 7", "Blue GND pin 5".
How do you go about terminating the RBG from J2 properly? What can this be connected to?
So the tuner will tune QPSK HDTV channels, which can be recorded or displayed with vdr-xine or softdevice, but the MPEG decoder won't output them. What's the best setup to use this then? Do you run vdr-xine or softdevice all the time and ignore the FF bit - to support TV and HDTV? Or just start vdr-xine when you tune to an HD channel? What does the MPEG decoder output when tuned to HDTV? Is there a better FF HDTV card with component/s-video MPEG decoder?

Component video is "color difference", S video is very similar to component, as there is a Y(luminance) but there are 2 color signals instead of one (R and B), the "difference" between R and B, makes G. RGB contains much more video bandwidth then component video. Svideo cannot handle HDTV, Component and RGB can.

Usually you need the filters and the termination resistors, and depending on where you live, RGB devices may or may not be common. (Think SCART)

I have 3 DVB-s cards in one machine, 1 is a FF, the other 2 are budget. I run in softmode using softdevice 100% of the time. Even though I don't receive and HDTV at all, using the output of a VGA card into a LCD projector produces a much better picture.
The advantage to the FF card, is that it will work in a slow computer as the card does all the work.
Displaying HDTV will need a powerful computer.

and you should be able to get better startup times I guess. I've been very impressed with the vdr-xine quality with DVB - except now I'm using pvr-input on a PVR-150. This is only a temporary measure until I get all the bits to build a DVB-S system.

I'm using a Shuttle PC with an s-video out. Since this can't be used for HDTV, maybe I need to look at getting a TV with VGA input - or find an RGB/Component card and buy a budget DVB-S. That leaves me with a PCI slot shortage. Hmm, maybe I need to rethink all this....
Thanks for your help, by the way....

I might hold off buying anything - the upcoming Hauppauge HVR-4000 looks like the one I'll want! HDTV in my home area is likely to follow the DVB-S2 route

Cool looking device, I just have too many questions :-) - Are they offering specs for the Linux driver development - Will there be models for the terrestrial and satellite broadcasts. (Is it btw. possible to receive HDTV over terrestrial...) - Does it do the processing in the hardware allowing it to run in a really slow computers like ff cards - Can it be connected to PCI bus or does it require something newer like this express something...

Me too!

I don't see why not?

Well, it's receiving pre-encoded MPEG2 on the DVB-S2/T, so there's little processing on the PC required. It appears to have an MPEG2 encoder for the analog, so again, little work on the PC. But it doesn't appear to have any MPEG decoder - so you'll still need vdr-xine or softdevice - which is fine by me, as that can potentially support HDTV and SDTV. But you do need a fair amount of PC horsepower to display HDTV.
Incidentally, is anyone out there using vdr-xine with HDTV? What kind of PC/hardware are you using? Any comments on quality etc??

As far as I can find out, it's regular PCI. There are some PCI-Express cards out there, but I have no need for them yet!!

Some DVB-S & MPEG-2 1080i demo channels still run on Sirius 5.0E. Works quite well with xine xxmc and 720p DVI/HDMI output to a LCD TV. The problem is that the HW deinterlacer in my FX5200 card is poor quality with some jagged moving edges. High quality SW deinterlacers such as GreedyH run only in "cheap" mode in my Sempron 3100+ CPU. Anyway cheap mode quality is not that bad.
My first tests with Nvidia 6200 and new HW deinterlacer look quite promising. I might also try 1080i mode with xxmc and deinterlacing in TV (5200 is not capable to 1080i trough DVI).
There is also support for MPEG-4 decoding in 6xxx 7xxx series nvidia cards but unfortunately not supported in Linux. Only MPEG-2 acceleration works.
I wish Klaus would upgrade some day to DVB-S2 and soft HDTV decoding :^)
Cheers, Seppo

DVB-S2: sure, once there are DVB-S2 cards with hardware MPEG-4 decoding.
Software HDTV decoding: I don't think so - that's what specialized and low power hardware chips are there for ;-)

I bought the "modded TT S2300 (rev2.3)" from DVB-shop and use it as my primary DVB-card. Works like a charm.
I've been using VDR with budget cards for a few years with vdr-xine. This will be my first FF with an MPEG decoder - any problems/advice on the quality of the RGB-out?
I've never got RGB to work fine with my TV (to high voltage even with the recommended resistors in place) so I'm using S-video instead which gives me much better picture.
Also, will this card support HD ok???
No. At least the MPEG decoder won't.
