Hey reelthing,
Because HDMI video signals and DVI signals are directly compatible, there should be little to no video quality loss if you wind up using a DVI-to-HDMI cable adaptor. Like hockeycanuckjc pointed out, however, DVI cables only support video signals - you’ll need to find another way to get an audio signal to your TV or home theater receiver.
If you want to avoid the hassle of multiple cables – or want the one of the newer DVD recorder boxes – you may want to give Brighthouse a call for more information. You never know, they may even offer a replacement HD cable box available that features an HDMI output!
Hope this helps you out!
