I am ready to begin building a mythtv environment. I have a few questions
before I get started.
I currently have the following
Toshiba H8016x9 TV, It has component inputs only ( I intend to purchase a
transcoder for vga to component video and use powerstrip) Zenith DTV 1080
HD Direct TV Receiver with SPDIF.
27" RCA TV with Svideo, Sony BT55 DirectTV
19" Samsung Flat Panel DVI monitor/Analog
12" Sony with only cable RF
I have purchased (1) PVR-250, (1) Wincast TV (848 chipset)
I am also going to purchase a PCHDTV, and other cards depending on answers
from you!
My questions are as follows.
1. I love the HD TV that is delivered from the Zenith HD DirectTV box. ( I
live directly across from NYC so I get all the HDTV channels available) I
could never ever go back to standard TV watching if I don't have to. The
guide integrates the ATSC with Satellite channels and is great for
previewing TV while I watch other channels.
a. I know that I will not be able to capture HDTV from the HD DirectTV, so
I will need to purchase the PCHDTV. Will the guide be integrated within
Myth. Will it remap channels (sub channels) ie CBS is 56-1 to 2-1 etc.....
Can I choose to exclude channels that have no signal?
b. The quality for the main TV is paramount. I know that DirecTV is highly
compressed so will I be able to capture that in at least 720x480. ( I am
sure the answer is yes). Can I scale that with FFDshow or Dscaler.
c. For the HD broadcast will I be able to capture full 1080i for 2,4,11 and
720p and 480p for ABC and Fox.
d. How does the sound work. The Zenith has optical out and analog out. I
have purchased a Mad Dog card with the Envy chipset and it has optical in
and out. Do I need to even bother with the optical in to get DD 5.1 for HD
broadcast or Direct TV. Will the capture card(s) just send the data over
the PCI bus? Or would I need to plug the optical in from the HD DirectTV
into the soundcard in and route optical out from my soundcard to my
receiver?
e. I intend to build separate backends and front ends. Therefore what is
the best configuration for this system. I concerned that the PCI bus won't
be able to handle all this from a central mammoth server. So I have
different scenarios which would make more sense?
Again image quality on the main RPTV is paramount.
i. build low end front end pII 333mhz with a (new purchase) PVR-350
that has Mpeg2 Hardware Encoder/Decoder and a PCHDTV for HDTV. I
would use a Radeon 9600xt or Geforce Ti200 for graphics card. I would use
the Envy card for audio. Lirc with a low speed data serial connection.
ii. or I would need much more powerful front end 2.6 ghz machine at
least for HDTV. Then I could run just a PVR 250 in a backend.
iii dont need to run anything on frontend except graphics card, so i
could go lowend with a nic card and pull everything from the backend of (2)
PVR-250s connected to (2)DirectTV's and a PCHDTV
iv. does the slave backend need a graphics card? Or could I load
up an old box that has scsi and ata 133 with multiple drives and just the
capture cards.
v. can I even use the Wincast TV card. It has composite video out
and analog out. Coud I use this without a graphics card? Will that be good
enough on the 27" TV.
vi. If intend to build a frontend only for the 27" TV and the
bedroom small TV do I need anything except for graphics card and sound cards
in those machines with minimal drives (9 gigs). What is the minimum configs
for front ends like this if I have a big backend with (2)PVR 250 and PCHDTV?
vii I like to channel surf and don't intend to completely Timeshift
all material. So if I wanted to watch Direct TV in one room while my wife
records something on another TV and watches Live TV is this possible. Or
would I need to have three PVR-250 connected to three DirectTV. Same
question for PCHDTV. Would I need to have two PCHDTV to watch LiveTV and
record. Would that crush the PCI bus? Does the box need to be superpowerful
for dual PCHDTVs
Your thoughts are greatly appreciated... Detailed responses are very
helpful. I have been reading the boards for months.
