My remote is now working with my TV after following the instructions on the link above. This went fairly smoothly.

After more testing of the Home Networking, I've identified a few issues.

Firstly, although I can use my TiVo to access pictures, music and video on the home PC, I cannot do this in the other direction. The problem seems to be that the 'Media access key' has still not installed from the central servers - the info screen reports 'not yet available'. A few forced connections have not resulted in the key arriving, so this can wait until tomorrow, by which time we should have a media access key reported.

Secondly, although I can pull various format video and audio from my PC, it appears that the Captions/Subtitle streams are omitted during the transfer. We have a multi-lingual household, so I have several recordings with subtitle streams (MKV or OGG Format) and these transfer fine but the subtitles are dropped. Its true that TiVo make no claim that MKV format is supported so I can't complain too loudly but I was hoping it would work since the video and audio come over correctly.

I have yet to try moving a recording with subtitles in the other direction. Possibly there is a different subtitle format I could use that would work.
