| Post subject: | Adding ATI HDTV Wonder to existing MythTv System? |
I recently purchased an ATI HDTV Wonder so that I can tune QAM channels from my cable operator (Charter). My existing MythTV has a master backend with the following specs: Knoppmyth R5F27 K7VTA3 Mobo Sempron 2500 CPU 512Mb PC2700 memory 500Gb HD 3 - PVR-150 Tuners connected to standard cable coax 1 - PVR-150 connected to digital tuner box via AV inputs (controlled via serial port for channel changes) I have two lineups with Schedules direct. 1) Standard cable channels, assigned to the 3 coax connected PVRs 2) Premium digital channels only, assigned to the tuner box PVR The system is very stable and has the ability to record from all 4 inputs simultaneously, as it is currently configured. What I would like to do is remove one of the coax connected PVRs, and install the ATI HDTV Wonder instead, so that I can access the clear QAM channels from my cable provider. This unit is used as a Master Backend only, and is not used for playback. There are 2 existing Frontend only machines currently in use, with a future expansion to 3 planned. My question is whether or not substituting the HDTV card for one of the existing PVRs will overtax the backend, which handles all recording, commercial flagging, and transcoding jobs. Would adding a slave backend be a better choice? Also, If anyone can shed any insights on the best way to add the third, HD only lineup from Schedules Direct, that would be very helpful as well.
