In addition to the usual RAI broadcasting I have found that the SAT Canaria TV is also showing some volleyball matches, it will be good to check it up especially when there are spanish teams playing (maybe their home matches) in the Champions league.
Also Planeta Sport is showing some matches. You can check their daily listing for the whole month on http://www.rtr-sport.ru/program.html?date=01.01.2007
the symbols help to see which ones are the volleyball matches. For the text I use http://babelfish.altavista.com/ for the translation. I have checked quickly for the next 2 weeks, these are the matches they are advertising (look up for the last one!):
4/1/07 00:05 Volleyball. League of Champions. Men. "buduchnost'" (Montenegro) - "Locomotive- Belogor'e" (Russia)
