THE Budget in Hongkong is rarely the cause of as much excitement as it is, say, in the US or Britain - the main question here usually being how big the surplus will be. However, predicted increases in tax allowances are likely to raise some interest. Both Pearl and World are broadcasting Financial Secretary Hamish Macleod's speech live (2.30pm) from Legco, and will have a 10-minute round-up of the contents in the evening (Pearl at 6.30pm, World at 7.25pm). And, should Mr Macleod deliver the goods and raise tax allowances, Robin Parke and Post racing editor Lawrence Wadey will provide advice for punters on how to dispose of that extra cash on Racing Night Live (World 9 pm). * * * * PEARL seems to have givenup trying to compete with the immensely popular racing, offering only the slow-moving Freeway (9.45pm, Original Running Time 91 mins) as an alternative. It's based on a series of real freeway murders in Los Angeles, but the film lacks any real conviction. A nurse (Darlanne Fluegel), whose husband was randomly killed by a freeway murderer, becomes obsessed with finding the killer herself when the police seem to be getting nowhere. Just to make it interesting, the perpetrator specialises in quoting from the Bible and phoning a radio psychiatrist from his car to let him know he's cruising LA looking for new victims. * * * * PRIME Sports are still ignoring the European Cup - despite the attractions of watching AC Milan play - in favour of the UEFA Cup. Their decision is causing much grief to the many Scottish fans in Hongkong, who are pining to watch the Rangers/Bruges match this evening. They'll have to console themselves with live coverage of the UEFA Cup quarter-final first leg match between Juventus and Benfica (Prime Sports 3.30am). * * * * MPINGO - The Tree That Makes Music (Pearl 8.30pm) examines the Tanzanian tree from which ebonycomes. The rhythms of Africa are played on ebony and it is used to make musical instruments all round the world. But the Mpingo has been over-exploited, the best trees cut down and new growth destroyed by dry-season grass fires. Like the elephant and rhino that roam the plains around it, the Mpingo is in danger of dying out and the Tanzanians who depend on it for their livelihood are facing ruin. * * * * IN Film '93 (BBC 7.25pm), Barry Norman reviews Lorenzo's Oil, a medically controversial film about parents desperately seeking a cure for their ailing son. It stars Nick Nolte and Susan Sarandon, who's been nominated for an Oscar for her role. He also discusses Honeymoon in Vegas with Nicholas Cage and James Caan, and Under Siege which stars Steven Siegal doing battle against hijackers on a ship. There's also a location report from, Splitting Heirs, the latest project from ex-Monty Python stalwart Eric Idle. * * * * PINT-sized Scottish pop dinosaur Lulu makes a guest appearance on Perfect Scoundrels (STAR Plus 8pm), playing Gossamer Trouble the widow of a gangster. Con artists Peter Bowles and Bryan Powers go to her husband's funeral and get an idea for a new scam.
