Many retailers had Shaw Direct HD receivers on sale over boxing week(s) sales, I saw the HDSR600 for $78, and the 630 for $247, so a new HDSR600 which has a built in modulator for the office or a 630 for the bedroom and then move the "old" but new 600 to the office.
Paying that extra $28 for a small footprint unit like the HDSR600 with a warranty might be better than driving a long way for a large used unit. Many retailers even included shipping. I'm sure they will be on sale again soon.
I suspect the 600 may one day have PVR capabilities as it uses the same software as the 630 which just got the EHD capabilities with the last software update. The previous is all just my opinion!
The 205 will still work for now, but is a legacy receiver, in that it uses the old grey guide (still usable, has the benefit of actually locking out channels and being able to surf only unlocked channels, plus turning off the banner), is QPSK, and MPEG2 only. For $10, it is okay until you can buy something else, or it fails and they replace. I use a 315 (same basic hardware as the 205) with my TiVo, and only miss having Bite and some HD only channels.
Ran a 25ft lead of RG6 from dish, hooked it to existing RG29 run to office. Had to install just one connector. Took a while for Shaw to get the receiver activated. Very helpful agent, but probably not so familiar with legacy receiver.
Only problem I have is with sound. Shaw remote will not change sound. When I use volume controls, the TV light (on remote) flashes, so it seems to be trying to communicate with TV, rather than via receiver. Old TV remote does adjust volume. I guess I will have to program the receiver remote.
I have tried a coax connection from 205 to TV as well as composite using just one side of audio output from receiver. Sound is a bit distorted both ways. May just be the TV.
I would like to thank you guys for being so helpful. Really useful information allowed me to get this done. Thanks!
