i'm gonna leave the FM issues to someone else who's more familiar, because all i know about XM/Sirius is that it sounds like shite
re: MPEG2--yes it is "lossy", since it utilizes compression...miniDV is compressed, as is HD...but you can't really compare video compression to audio compression, it's a whole different animal...in layman's terms, there is no such thing as lossless video, and i don't see it happening anytime soon--maybe 50 yrs down the road, but even then i doubt due to other issues we'll skip for now...basically, the amount of data raw video would take up would be ridiculous and the "cons" would far outway the "pros"...
i will note--when it comes to MPEG2 compression, i do believe the program used makes a difference...some perform far better than others in terms of artifacts, video noise, etc...and it goes without saying, the bitrate plays a key role as well...video compression is definitely a "you get what you pay for" thing
